Question
The current age ratio of
'Ganesh', 'Hitesh', and 'Indira' is 5:7:6. In 8 years, the ratio of the ages of 'Ganesh' and 'Hitesh' will be 4:5. Determine the present age of 'Indira'.Solution
ATQ, (5x+8)/(7x+8)=4/5 Cross-multiplying gives: 5(5x+8)=4(7x+8) Or, 25x+40=28x+32 Therefore, 3x=8 So, x = 8/3 Present age of 'Indira' = {6 × (8/3)} = 16 years
36895 - 4256 - 2233 = ?Â
Find the simplified value of the following expression:
[{12 + (13 × 4 ÷ 2 ÷ 2) × 5 – 8} + 13 of 8]
- Simplify:

(21 X 5) + ? = (480 - 120) ÷ 3
What will come in the place of question mark (?) in the given expression?
34 X 11 - ? + 36 = 3 X 75 + 125
- What will come in the place of question mark (?) in the given expression?
(√1089 + 47) X 4.5 = ? - √256 X 10 62 + 43 + 625(1/4) - ? = 102
625 × (?% ÷ 125) = 250% of 10
3 √8 × √36 × 13 = ? × √169
81 ÷ 0.09 × 1.4 – 1223=?
