4. Michael owes P25,000 due in 1 year and P75,000 due in 4 years. He agrees to pay

P50,000 today and the balance in 2 years. How much must he pay at the end of two

years if money is worth 5% compounded semi-annually?

3. A machine costs P20,000 today. If inflation rate is 6% per year and interest is 10% per

year, what will be the appropriate future value of the machine, adjusted for inflation, in

five years?

1. Determine the accumulated value of P2000.00 in 5 years if it is invested at 11%

1.) An equipment costing P250,000 has an estimated life of 15 years with a book value of P30,000 at the end of the period. Compute the depreciation charge and its book value after 10 years using the sum of years digit method.

Answer;

d = P11,000 BV = P57,500

A magnetic circuit consists of silicon steel of 3000 permeability, of 10 cm length and a 2

cm air gap. Both have the same cross section of 1.5 cm. A current of 0.5 A is needed to

flow through the coil in order to produce a flux of 2351 Mx. Find the number of turns in

the coil.
