Question

1. Sum of three numbers is 136. If the ratio
between first and second be 2:3 and that
between second and third is 5:3, then the second
number is
a) 40
c) 72
b) 48
d) 60​

Answer 1

Answer:60

Let the three numbers be a, b and c respectively. 

Now. 

a : b = 2 : 3 

b : c = 5 : 3 

Therefore, a : b : c = 2×5:3×5:3×32×5:3×5:3×3

= 10 : 15 : 9 

According to the question,

a + b + c = 136

=> 10x + 15x + 9x = 136

=> 34x = 136 => x = 13634=413634=4

Therefore, b = 15x = 15×415×4 = 60

Hope this helps you
