Question
A quantity is increased by 25% and afterward decreased by
10%. What is the overall percentage change in the original quantity?Solution
ATQ,
Let the quantity be '100b'
Final quantity = 1.25 Ă— 0.9 Ă— 100b = '112.5b'
Required percentage increase = [(112.5b - 100b) Ă· 100b] Ă— 100 = 12.5%
1555.5 + 1000.8 – 1354.3 = ? + 52
What will come in the place of question mark (?) in the given expression?
24% of 350 + 246 = ? + 50 Ă— 2.5
115% of 40 + 3 × 4 = ? × 11 – 8

(200 + 50% of 120) Ă· (9 Ă— 2) = ?
1540 ÷ 7 - 184 ÷ 8 = ?
5.45% of 1854 – 37.5% of 1096 = ? – 48% of 630
22% of 560 + 34% of 2160 Ă— 5/12 =? + 16% of 920
36895 - 4256 - 2233 = ?Â
