_____________________________________

He bought 22 stamps.

------------------------------------------

Clear Explanation:-

Given,

Cost of stamp-20p & 50p

Total cost- £9.90.

So,

Number of 20p stamps is twice as number of 50p stamps so for each 50p another 40p spent for a total of 3 stamps.

Each 3 such number is equivalent of 2*20p+50p=90p

And there are £9.90/90p=11 number of 90p's fit in total price.

So, Total number of stamps=11*3=33

Amount of 20p stamps-2/3 of 33 = 22.

→ Hence, no.of Stamps He bought = 22
