Arko is twice as old as Adeeb. Eight years ago, Arko was 6 years younger than three times Adeeb's age at that time. How old will Arko be in 5 years?

A 45

B 47

C 49

D 53

Solution

Correct Answer: Option C

মনেকরি,
Adeeb এর বর্তমান বয়স = x বছর
Arko এর বর্তমান বয়স = 2x বছর

প্রশ্নমতে, 3(x - 8) = 2x - 8 + 6
=> 3x - 24 = 2x - 2
=> 3x - 2x = -2 + 24
=> x = 22

∴ 5 বছর পরে Arko এর বয়স = 2x + 5
= 2.22 + 5
= 44 + 5
= 49
