Question
What is to be subtracted from (13/20) so that the result is
(7/25)?Solution
ATQ,
Let the required number be 'x'
(13/20) - x = (7/25)
Or, x = (13/20) - (7/25)
Or, x = {(325 - 140)/500}
So, x = (185/500)
30% of 200 – 20% of 50 = 10% of ?
?3 - 25 × 11 = 30 - 15 × 12
Simplify the following expressions and choose the correct option.
(45% of 640) ÷ 8 + (3/4 of 96) = ?
- What will come in the place of question mark (?) in the given expression?
(15 - 19 + 10) ² + ? = 45 X 2 - 48% of 300 – 24% of 150 = 12% of ?

36% of 250 + 26 ÷ 2 × ? = 207
10 × 100 ÷ 5 + 9 = ?
What will come in the place of question mark (?) in the given expression?
? = (27 × 13) – 26% of (412 – 92 )
