A body of 7300 troops is formed of 4 battalions so that `1/2` of the first, `2/3` of the second, `3/4` of the third and `4/5` of the fourth are all composed of the same number of men. How many men are there in the second battalion? (a) 1500 (b) 1600 (c) 1800 (d) 2400

The sum of three numbers is 67. If the ratio of the first number to the second number is 3:5 and that of the second to the third is 4:7, then what is the second number? (a)20 (b)24 (c)18 (d)16

Of the three numbers,the ratio of the first and the second is 8:9 and that of the second and third is 3:4. If the product of the first and third numbers is 2400, then what is the second number?

There are 43800 students in 4 schools of a city. If half of the first, two -third of the second, three fourth of the third and four -fifth of the fourth are the same number of students, then find the ratio of number of students of A and D if A,B,C and D be the first, second, third and fourth schools respectively.

Of the four members, the first is twice the second, the second is one-third of the third and the third is 5 times the fourth. The average of the numbers is 24.75. The largest of these numbers is (a) 9 (b) 25 (c) 30 (d) None of these

The sum of three numbers is 98. If the ratio of the first to the second is 2 : 3 and that of the second to the third is 5 : 8, then the second number is:

How many pairs of number exist such that their HCF is 4 and LCM is 48 ? (a)2 (b)1 (c)3 (d)4
