Question

Apples contain 1 rupee 50 paise and 25 paise coins in the ratio 7 is to 8 is 29 is the total money in the purse is 159 the number of 50 paise coins in the purse will be

Answer 1

1 paise = 0.01 Rupees

Convert the paise to Rupees :

50 × 0. 01 = 0.5 Rupees

25 × 0.01 = 0.25 Rupees

Let the total number of coins be x then :

Since the ratio of 1 rupee : 50 paise : 25 paise is :

7 : 8 : 29

The sum of the ratios is :

7 + 8 + 29 = 44

50 paise = 8/44x

1 rupee = 7/44x

25 paise = 29/44x

Their total value is :

8/44x × 0.5 + 7/44x + 29/44x × 0.25 = 73/176x

73/176x = 159

73x = 159 × 176 =

73x = 27984

x = 383.3

Approximately 383

50 Paise coins are :

8/44 × 383 = 69.63

Approximately 70
