Question

Last year the cost of 1 kg of onion was Rs 45. This year, the cost of the onion increased to Rs 60. What is the percentage change in its price?

Answer 1

Last year,
The cost of 1 kg of onion = Rs 45.
Present year,
The cost of the onion = Rs 60
Increase in cost = Increased price – old price = 60 – 45 = Rs 15 Increase cost = Rs 15
Increased % $=\frac{\text{Increase cost}}{\text{Old Price}}\times 100$
$=\frac{15}{45}\times 100=33.33\%.$
