1. A is two years older than B who is twice as old as C. If the total of the ages of A, B and C be 27, then how old is B?
- A. 7
- B. 7
- C. 7
- D. 7
Answer: Option D
Explanation:
ধরি, C এর বয়স x বছর
B এর বয়স। 2x বছর
A এর বয়স = ( 2x + 2) বছর
x + 2x + 2x + 2 = 27
5x = 27 - 2
x = 25/5
x = 5
B এর বয়স ( 2 ×5) বছর = 10 বছর
