Discount = 15% of 80

= 0.15 * 80

= 12

Sale price = Original price - Discount

= 80 - 12

= 68

Explanation

Given that x added to itself 13 times gives 112:

x + 13x = 112

14x = 112

x = 112 / 14

x = 8

Explanation

Work done by 12 children in 16 days = 1 (full work)

Work done by 1 child in 16 days = 1/12

Work done by 1 child in 1 day = 1/(12 × 16) = 1/192

Work done by 8 adults in 12 days = 1

Work done by 1 adult in 12 days = 1/8

Work done by 1 adult in 1 day = 1/(8 × 12) = 1/96

Work done by 16 adults in 3 days = 16 × 3 × (1/96) = 1/2

Remaining work = 1 - 1/2 = 1/2

Now, 6 adults and 4 children work together:

Work done by 6 adults in 1 day = 6 × 1/96 = 6/96 = 1/16

Work done by 4 children in 1 day = 4 × 1/192 = 4/192 = 1/48

Total work done per day = (1/16 + 1/48) = (3 + 1)/48 = 4/48 = 1/12

Days required = (1/2) ÷ (1/12) = 6 days
