a. 95
b. 70
c. 100
d. 140
e. 35


b. 70
Explanation in detail:
Let the number be x.
(3x/5) × (7/5) – (2x/5) × (3/4) = 108
(21x/25) – (6x/20) = 108
27x/50 = 108
So, x = 200
Required answer = (7/20) × 200 = 70

c. 22
Explanation in detail:
Let the first number be x.
x + (x + 1) + (x + 2) + (x + 3) + (x + 4) + (x + 5) = 129
6x + 15 = 129
x = 19
