Question
Amit is 6 years older than Sahil. The present age ratio of
Sahil to Rohan is 7:4. Additionally, Amit’s current age is twice that of Rohan’s. Based on this information, determine Sahil’s present age.Solution
ATQ;
Let Sahil’s present age = 7x years 
Rohan’s present age = 4x years 
Amit’s present age = 7x + 6 
According to the question, 
(7x + 6) = 2 × 4x 
7x + 6 = 8x 
x = 6 
Present age of Sahil = 7 × 6 = 42 years
[(4/3) + (5/6)] of 378 = ?
? = 80% of 30% of (50 × 150) + 400
What will come in the place of question mark (?) in the given expression?
(144 × 16 ÷ 12) × 6 = ?
Find the value of (x + y)² - (x - y)², where x = 15 and y = 7.
[4(2/3) + 5(1/6)] × 45% of 240 = ?
20.05% of 220.05 – 15.15% of 99.99 × 2.02 = ?
What will come in the place of question mark (?) in the given expression?
? X (62 - 20) + 60 X 5 = √1296 X 25 - 35 X 43...
?% of 320 - 69 = 123
