The LCM of three positive integers X, Y and Z is 119^2. Find the total number of ordered triplets.

Hi Diwas,119^2 = 7^2 * 17^2 Let (x, y, z) be the tripletSo, at least one number in this triplet must have 7^2 in it.And, at least one number must have 17^2Let's consider 7^2 Let's find the number of triplets possible whose LCM = 7^2(7^2, 7^0, 7^0) - 3 ways(7^2, 7^1, 7^0) - 6 ways(7^2, 7^1, 7^1) - 3 ways(7^2, 7^2, 7^0) - 3 ways(7^2, 7^2, 7^1) - 3 ways(7^2, 7^2, 7^2) - 1 wayTotal = 19 daysSimilarly, we get 19 ways for 17^2Therefore, total number of triplets possible = 19*19 = 361.Hope this helpsThanks

‘X’ is the largest sum of rupees which can never be paid using any number of coins of denominations Rs.4, Rs.8, Rs.13 and Rs.18. What is the sum of the digits of ‘X’? Kindly provide a detailed solution

Hi Anushree,You also need to mention the number of digits in the number. Moreover, can all the denominations be used together or only 1 denomination is used at a time?

A rectangle is drawn such that none of its side has length greater than `a'. All lengths less than 'a' are equally likely. The chance that the rectangle has its diagonal greater than 'a' is(in terms of %)

Hi,Can you please post the original question. The question seems a bit unclear.

Any stratergy to prepare for pj'"s?

Hi Karthik, There are few concepts to keep in mind while attempting Para Jumbles. 1. Try to find Main Point of the paragraph. Every paragraph has an idea or a soul which should be identified. The sentences when constructed in the correct order reflect that idea. Try to find that idea and see what role a particular sentence will play in depicting the entire picture. Then arrange them accordingly to make paragraph coherent. 2. Try to see verbal connectives and logical connectives. These give hints regarding the sentences which follow and help in constucting a paragraph logically. 3. Try to see analogies as they should proceed with real life examples. Hope this will help you. All the best.

I am how to prepare puzzle

Two friends A and B start on a circular track at the same time in the same direction. If the speed of A is 12m/s and both A and B meet only at starting point, how many values can the speed of B take if the speed of B is less than 30 m/s. The answer given is 11 times. I am not able to get the solution. Can anyone help please.

A=12m/s,B<30m/s , becoz they are travelling in SAME direction therefore we will subtract their speed i.e (12- x)m/s ,,,, then we know that a and b meet only at starting point therefore a:b=1(met once) (u can refer mock test 12 of ibps po ) hence 12-x should be 1,,,,, so (12-x)=1 i.e 11 so b can take 11 values if they meet only once in their track! :)
