Question

A street vendor has enough money to buy 20 pairs of shoes. If he gets discount of Rs. 25 on each pair of shoe, then he can buy two more pairs of shoes, and still have Rs. 70 left with him. How much money did he have originally?​

Answer 1

Total original amount with him is Rs 400

Answer 2

Solution :-

Let us assume that, originally the vendor have Rs.x .

so,

→ Total pairs of shoes he buy = 20 pairs .

then,

→ CP of each pair of shoes = Rs.(x/20)

now,

→ New CP of each pair of shoes = Rs.{(x/20) - 25}

and,

→ Total pair of shoes he buy now = 20 + 2 = 22 pairs

A/q,

→ 22{(x/20) - 25} = (x - 70)

→ 22(x - 500)/20 = (x - 70)

→ 22x - 11000 = 20x - 1400

→ 22x - 20x = 9600

→ 2x = 9600

→ x = Rs.4800 (Ans.)

Hence, originally the vendor have Rs.4800 .
