A bag contains 700 coins of 25p denomination and 1400
coins of 50p denominations. If 17% of 25p coins and 34% of 50p coins are removed, the percentage of money removed from the bag is nearly? Â ÂSolution
Total money = Rs.[700 x (25/100) + 1400 x (50/100)] = Rs. 875 25 paise coins removed = Rs. (700 x 17%) = 119 50 paise coins removed = Rs. (1400 x 34%) = 476 Money removed =Rs. {119 x (25/100) + 476 x (50/100)} = Rs. 267.75 Required percentage = (267.75/875) x 100 = 30.6%

(74.93% of 640.11 + 3/4 of 359.79)² - (1/3 of 80.87 × 2)² = ?
[(120.96 × 12.09) ÷ ?] ÷ 6 = 19.96% of 55.07
620.15 + 1279.98 + ? × (4.79)2 = 149.95% of 1600.14
(8.86)² × (15.01)² ÷ √624.99 = 9?
(√360.99 + 161.14) ÷ 5 × 249.98 = ?
420.11 ÷ 13.98 × 5.14 – 124.9 = √?Â
