Question

A shopkeeper purchased the basket of 400eggs out of them 28 eggsrotten the remaining eggs he sold at rupees 48 Per dozen if he gain 4 per cent then find his cost price

Answer 1

Total number of eggs = 400

Find the total number of eggs left after 28 was rotten:

Total number of eggs = 400 - 28 = 372

Find the selling price:

372 eggs = 372 ÷ 12 = 31 dozens

1 dozen eggs = Rs 48

31 dozen eggs = 48 x 31 =  Rs 1488

Find the cost price:

Gain = 4%

Selling Price = 100 + 4 = 104%

104% = Rs 1488

100% = (1488 ÷ 104) x 100  

100% =  Rs 1430.77

Answer: The cost price is Rs 1430.77

SHORTCUT:

Selling Price = (400 - 28)/12 x 48 =  Rs 1488

Cost Price = 1488/104 x 100 = Rs 1430.77
