Question
Bheem is currently 25 years old, which is 25% more than
Ayush’s present age. The average of Ayush and Chintu’s present ages is 34 years. Additionally, the present age ratio of Chintu to Dinesh is 3:5. Determine the age difference between Bheem and Dinesh.Solution
ATQ, Present age of ‘Ayush’ = 25/1.25 = 20 years Present age of ‘Chintu’ = 2 × 34 – 20 = 68 – 20 = 48 years Present age of ‘Dinesh’ = 48 × (5/3) = 80 years Required difference = 80 – 25 = 55 years
Evaluate:
√729 + √49 - √16 + 1/√64
Simplify:

(1/5)(40% of 800 – 120) = ? × 5
2/5 of 3/4 of 7/9 of 7200 = ?
`sqrt(5476)` + 40% of 1640 = ? `xx` 4 - 2020
? = (22% of 25% of 60% of 3000) + 21
Determine the simplified value of the given mathematical expression.
(342 – 20% of 5280) = ? ÷ 3
∛157464 =?
