Discount = 40

Selling price after single discount = 60

Selling price after two Successive discount = 64

Difference Percentage = 4%

2). Answer: c)

1/A + 1/B = 1/ 10 days

1/C + 1/ A = 1/ 12 days

2(1/A + 1/B+1/C) =1/4 days

A + B + C = 1/ 8 days

(A+B+C) โ (A+ B) = 1/ 8 โ 1/10 = 40 days

C = 40 days
