1 Answer

Answer :

240×1 ÷ 180 = 4/3
12÷ 4 × (240 × 1 ÷ 180) = 3 × (4/3) = 4
101 + 98 ÷ 7 – 113 = 101 + 14 – 113 = 2
19 + (12 ÷ 4 × (240 × 1 ÷ 180)) × 6 ÷ (101 + 98 ÷ 7 - 113) = 19 + 4 × 6 ÷ 2
= 19 + 4 × 3 = 31
7÷2 + 14 – 3.5 – 9 × 8.5 = 3.5 + 14 – 3.5 – 76.5 = -62.5
(7÷2 + 14 – 3.5 – 9 × 8.5) × 4 = - 62.5 × 4 = -250
19 + (12 ÷ 4 × (240 × 1 ÷ 180)) × 6 ÷ (101 + 98 ÷ 7 - 113) – (7÷2 + 14 – 3.5 – 9 × 8.5) ×
4
= 31 – (-250) = 281

Sush was thrice as old as Poonam 6 years back. Sush will be 5/3 times as old as Poonam 6 years hence. How old is Poonam today? A.20 B.14 C.12 D.15 E.None of these

Description : Sush was thrice as old as Poonam 6 years back. Sush will be 5/3 times as old as Poonam 6 years hence. How old is Poonam today? A.20 B.14 C.12 D.15 E.None of these

Last Answer : Answer – C (12) Explanation – Let Poonam age 6 years back = x. Then, Sush age 6 years back = 3x. (5/3) * (X + 6 + 6) = (3X + 6 + 6) So 5(x+ 12) = 3(3x+ 12), so x=6. Poonam Age = (x+ 6) years = 12 years
