Question
‘S’ has 20% fewer books than ‘T’. ‘T’ has 25%
more books than ‘U’. By how much percent are the books with ‘S’ less than those with ‘U’?Solution
ATQ,
Let, number of books with ‘T’ = 25b
Number of books with ‘S’ = 0.8 × 25b = 20b
Number of books with ‘U’ = (25b/1.25) = 20b
So, required percentage = {(20b – 20b)/20b} × 100 = 0%

280 – 70 × 14 ÷ 5 = ? – 21 of 3
- What will come in place of (?) in the given expression.
(18.5 × 2) + (3.5 × 4) = ? 4.5 times 5/0.9× 35% of 240 =?
144% of 200 + 11% of 900 + 10% of 20 =?
Find the value of 'p' in the given expression: 15 of 6 ÷ p x 4 = 30.
300% of (3341 – 471) = ? × (√4225/195)
What will come in the place of question mark (?) in the given expression?
? = (27 × 13) – 26% of (412 – 92 )
What will come in the place of question mark (?) in the given expression?
(87 + 79) X √9 - 298 = ? + √3600
(1/5){(2/5) × 400 + 20% of 150} = ?
