18. The price value of the share of a company increased at the rate of 15% in the first year, suffered a loss of 10% in the next year and again increased by 20% in the third year. If the present value of the share is 2000, what will be its value after 3 years

The present price is $2000
In the first year, the share price increases by 15%. To find the new value after the first year, we need to add 15% of $2000 to the present value:

New Value =2000 + 2000 x 15%
= 2000 x 2000 x 15/100
= 2000 + 300
= 2300

This will also be the starting price for the second year

In the second year the share value fell by 10% from 2300. We have to subtract 2300 x 10% from 2300 to get the value at the end of the second year

Value at end of second year (same as value at beginning of third year)
= 2300 - 2300 x 10%
= 2300 x 2300 x 10/100
= 2300 - 230
= 2070

In the third year, share value increased by 20%
Value at end of third year = 2070 + 2070x 20/100
= 2070 + 414
= 2,484
Value at the end of the third year = 2070 (1.20) = 2,484
