Answer 2

Answer:

fisrt we find the price for one shirt

let it be y

50 ↔ 30,000

1 ↔ y

by cross multiplying

50y=30,000

50 50

y=600

∴one shirt costs 600

10 will cost

10×600

6000

loss of 10% of 10 shirts

loss=10 × 6000

100

loss=600

profit of each shirt

30 × 600 = 180

100

he should sell each shirt at

buying price + profit

600+180

780

should sell the remaining shirts at

40 × 780

31200
