1. If the income of A is 10% more than that of B and the income of B is 20% less than that of C, then the income of A, B and C respectively are in the ratio

  • A. 22 : 18 : 25
  • B. 22 : 18 : 25
  • C. 22 : 18 : 25
  • D. 22 : 18 : 25

Answer: Option B

Explanation:

ধরি, C এর ইনকাম 100 টাকা

B এর ইনকাম ( 100 - 100 এর 20%) = 80 টাকা

A এর ইনকাম ( 80 + 80 এর 10 %) = 88 টাকা।

A : B : C = 88 : 80 : 100 = 22 : 20 : 25
