₹1442.50
Step-by-step explanation:
Given:
Principal = 163840 ; Rate = 12.5 %
So, A = P(1+r/100)n
= 163840(1+12.5/100)2
= 163840(112.5/100)2
= 2048 * 22.5 * 4.5 = 207360.
CI per annum = 207360 - 163840 = 43520.
CI half yearly r = 12.5/2= 6.25
A = P(1+r/100)n
= 163840(1+6.25/100)4
= 163840(106.25/100)4
= 208802.5
CI half yearly = 208802.5 - 163840 = 44962.5
Gain after 2 years = 44962.5 - 43520 = ₹1442.50
