# How Many Stamp were Purchased by Man?

A man purchased 147 stamp of 60-paisa and 35 paisa. The total amount he spent was Rs. 68.20. How many 35-paisa stamps were purchased by him?

- 60
- 72
- 76
- 80

**Answer: (4) 80**

**Explanation:-**

Let the number of stamps be X which cost of a stamp is 60 p & the number of stamps Y which cost of a stamp is 35 p.

The total number of stamp = 167

Then, X + Y = 167 …………………….. (1)

The total cost of stamps = Rs.68.20

Then, 60 X + 35 Y = 167

Divide by 5 ,

12 X + 7 Y = 13.64 …………….. (2)

Solve equation (1) & (2) ,

X = 67 & Y = 80

Then, the number of 35-paisa stamps is 80.

Hence, the answer is (4) 80.
