Question

Keeping the printed price of Rs.5 per pen, 10% discount was given to the customer. In this transaction profit of 12.5% was gained and Rs.1800 earned. How many gross pens were sold? *

Answer 1

$\large\bf{\underbrace{\red{SOLUTION:-}}}$

Marked Price = Rs 5

Find the price after discount :-

Discount = 10% of 5 = Rs 0.50

Price after discount = 5 - 0.5 = Rs 4.50

Find the profit :-

Profit = 12.5%

=> Selling Price = 100 + 12.5 = 112.5%

▼ Selling Price = Rs 4.50

Now,

☞ 112.5% = 4.50

☞ 1% = 4.5 ÷ 112.5 = Rs 0.04

☞ 12.5% = 0.04 x 12.5 = Rs 0.50

Find the number of pens bought :-

✪ Number of pens = 1800 ÷ 0.50 = 3600
