Ben borrowed 20,000 pesos from Glennand promised to pay him after 3 years with and interest of 5% compounded annually. On the 3rd year, exact date of his payment, Ben requested to extend his deadline for another 2 years. Glenn being a considerate man, agreed but under the new condition that from then on, the interest shall be 6% compounded semi-annually. Two years later, on exact deadline, Ben asked Glenn, again, for 1 more year. He also borrowed an additional 12,000 pesos with 2% interest compounded quarterly from Glenn. He promised that he will pay everything (principal and interest) on the exact deadline. How Much will Ben pay in total?
