Question

he sum of three numbers is 136. If the ratio between first and second is 2:3 and that
between second and third is 5:3. Find the second number.

Answer 1

Answer: 60

Step-by-step explanation:

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

Now.

a : b = 2 : 3

b : c = 5 : 3

Therefore, a : b : c = 2×5:3×5:3×3

= 10 : 15 : 9

According to the question,

a + b + c = 136

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

=> 34x = 136 => x = 13634=4

Therefore, b = 15x = 15×4 = 60

Answer 2

Step-by-step explanation:

let the three numbers be a,b,c respectively

Now.

a:b=2:3

b:c=5:3

a:b:c=10:15:9
