A certain amount earns simple interest of 1750 after 7 years. Had the interest been 2% more, how much more interest would it have earned? Choose the correct choice
A) 35	B) 350	C) 245	D) Cannot be determined	E) None of these
Let p and r be the principal amount and rate of interest respectively.   Then, p×r×7/100=1750   or, pr = 25000   Now, SI = p×(r+2)×7/100=1750   We have to find the value of   p×(r+2)×7/100−p×r×7/100= M - 1750   M = SI when the rate of interest is 2% more. When we solve this equation, we find that we have two variables and one equation. Therefore, can’t be determined the correct answer.   Answer Cannot be determined
