• 1Rs. 31.11
• 2Rs. 29.22
• 3Rs. 33.11
• 4Rs. 32.22
Explanation:-

Solution:
Money spent originally = Rs. 140.
Less Money to be spent now,
= 10% of 140
= Rs. 14
Rs. 14 now yield 500gm sugar.
So, Present rate of sugar = Rs. 28 per kg.
If the present value is Rs. 90, the original value
= Rs. 100.
If the present value is Rs. 28 the original value,
= Rs. (1 0 0/9 0)*2 8 = Rs. 31.11.
