numbers can be split into 1mod9,2mod9.. 0mod9(remainder when divided by 9). (1,8) (2,7) (3,6)(4,5) (0,0) make pairs which add upto 9. so only one of these pairs has to be chosen. Hence the answer is (333*4+3+1)= 1336

**All you need to know about US's Mother of All Bombs**

The United States on April 13, 2017, dropped a massive GBU-43 bomb in eastern Afghanistan against a series of caves used by Islamic State militants. According to the Afghanistan officials, the bomb killed over 30 Islamic State militants in the area.

What is the GBU-43 bomb?

The Massive Ordnance Air Blast bomb (MOAB) also known as the ‘mother of all bombs’ is the largest non-nuclear bomb ever deployed in combat by the United States. The GBU-43 is a 21,600 pound (9,797 kg) GPS-guided munition and was first tested in March 2003, just days before the start of the Iraq war. It is a demolition bomb containing 18,700 pounds (8,480 kilogrammes) of the explosive H6, with a blast yield equivalent to 11 tonns of TNT. Nine metres (30 feet) long, with a diameter of one metre, according to GlobalSecurity.org, it is the largest-ever satellite-guided, air-delivered weapon in history.

What was the MOAB designed for?

The MOAB is a custom-made Air Force weapon that has been in the arsenal for more than a decade. It is designed to hit softer targets such as surface facilities, tunnel entrances and troop concentrations. It is a concussive bomb, meaning it is designed to detonate before it hits the ground. Its thin aluminium skin helps to maximise its blast radius and generate a shockwave, according to Wired.com.

How is the MOAB deployed?

The MOAB is dropped off from the cargo ramp of a C-130 transport plane with its descent slowed by parachute. This means it can be deployed from a greater height, thereby offering pilots more time to reach safety.

What is the Pentagon's view on the MOAB?

In the Pentagon's 2003 review of the legality of using the MOAB, it was concluded that it could not be called an indiscriminate killer under the Law of Armed Conflict.

“Although the MOAB weapon leaves a large footprint, it is discriminate and requires a deliberate launching toward the target,” the review said. It added, “It is expected that the weapon will have a substantial psychological effect on those who witness its use.”

Who made the bomb?

The MOAB was developed in 2002-2003 by Alabama-based aerospace and defence company Dynetics in partnership with the Air Force Research Lab (AFRL), according to the company's website. The website said the bomb's preliminary concept was developed into a detailed design within just three months, and successfully tested three times in 13 days. According to the Air Force, the last time the MOAB was tested in 2003, a huge mushroom cloud could be seen from 32 km away.

This is a very broad question. A best approach to start will be to plan where you are and where you want to reach by the end of one week. I would highly recommend picking up one standard book (Rec. R S Agarwal) and picking up a favorite topic (Rec. Easy and interesting) and take evaluatory tests. Look at what mistake you make. Look at what part of the problem is challenging for you. Now, you have a dragon to slay. Time that for one week. Dont run behind new methods or techniques. Build on ur strengths. Practice and win over your weaknesses. By the end of 1 week, you should be able to solve better and make lesser mistakes. Choose your material and choose the problems you want to solve. No standard one-solution-works-for-all method here. If you need more help, feel free to check out my profile. Thanks. read less

Theoretically, you need 3 equations to solve linear equations with 3 variables. In this question, you are given only two equations with three variables. That means this problem comes under special equations. Depending upon the nature of the equations you have to apply special technique to solve special equation. Here, I apply one such special technique: 3x+5y+7z=49 (1) 5x+8y+11z=78 (2) multiply the first equation with 3 9x+15y+21z=147 (3) multiply the second equation with 2 10x+16x+22z=156 Now, subtract (3) from (2) x+y+z=9 read less

Let the CP of the article be Rs. x, since he earns a profit of 20%, hence SP= X + 20% of X = 1.2x. It is given that he incurs loss by selling 16 articles at the cost of 12 articles [loss = (16-12)/16 = 25%] His selling price = SP - 25% of SP = SP*0.75; Hence, SP*0.75 = 1.2X.

Or, SP = (1.2*x/0.75) = 1.6X. This SP is arrived after giving a discount of 20% on MP. Let MP = Y. Y - 20% of Y = SP 0.80Y = 1.6X. Y = 2X. It means that the article has been marked 100% above the cost price. Or Marked Price was twice of cost price. read less
