A certain amount earns simple interest of Rs. 1750 after 7 years. Had the interest been 2% more for first 5 years, how much he will get now at the end of 7 years ?

To calculate simple interest at different rates, we need the principal amount. The problem only states that Rs. 1750 is earned after 7 years at some rate, but doesn't specify the principal or the original rate. Without knowing whether 2% more means (r+2)% or 1.02r, and without the principal value, the interest cannot be determined.
