Question

If due to 10% decrease in the price of sugar,
Ram can buy 5 kg more sugar in rupees 100, then find the
actual price of sugar.​

Answer 1

Answer:

₹ 20/9 per kg

Step-by-step explanation:

Initial situation:

100 rupees can buy x kg sugar. (say)

Situation after decrease in rate:

100 - 10% × 100 can buy x kg sugar now.

100 rupees can buy x + 5 kg sugar.

So, (100 – 10)(x + 5) = 100x

or, 90x + 450 = 100x

or, 10x = 450

So, x = 45

Hence, actually sugar was 100 rupees per 45 kg, i.e., (20/9) rupees per kg.
