Primary Divisonal 2012/5

Once upon a time there was a shop which sold a packet of five sweets for \$10\$ taka. But if someone bought less than five sweets, they would take \$3\$ taka for each sweet. What was the price of \$39\$ sweets?

5 sweets for 10 taka. 35 sweets for 70 taka.
1 sweet for 3 taka. 4 sweets for 12 taka.
(35+4)or 39 sweets for (70+12) or 82 taka.
So, ans is 82 taka.
