Answer
(1) Price on April 2
Given:
Opening price (April 1) = ₹2552
Change = gain of ₹37
Price on April 2 = ₹2552 + ₹37 = ₹2589
Hence, option 2 is the correct option.
(2) Price by the end of April 3
Given:
Change 1 = Loss of ₹16
Change 2 = Loss of ₹8
Total loss = ₹16 + ₹8 = ₹24
Price on April 2 = ₹2589 (from the previous step)
Price by the end of April 3 = Price on April 2 - Total loss
Substituting the values, we get:
Price by the end of April 3 = ₹2589 - ₹24 = ₹2565
Hence, option 2 is the correct option.
(3) Price by the end of April 4
Given:
Change 1 = Gain of ₹11
Change 2 = Gain of ₹14
Total Gain = ₹11 + ₹14 = ₹25
Price on April 3 = ₹2565 (from the previous step)
Price by the end of April 4 = Price on April 3 + Total Gain
Substituting the values, we get:
Price by the end of April 4 = ₹2565 + ₹25 = ₹2590
Hence, option 3 is the correct option.
(4) Price by the end of April 5
Given:
Change 1 = Loss of ₹13
Change 2 = Gain of ₹4
Price on April 4 = ₹2590 (from the previous step)
Price by the end of April 5 = ₹2590 - ₹13 + ₹4 = ₹2581
Hence, option 4 is the correct option.
