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?Solution
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%
