COMPOUND INTEREST. 
94. To find the Amount of a sum in any number of years. 
Look in Table 3, under the given rate per cent opposite the number 
of years for the amount of £l, then multiply it by the sum of which the 
amount is required. 
Example. Required the amount of ¿£835 in 12 years at 4^ per cent 
compound interest. 
In Table 3, under 4^ per cent opposite 12 years, we find 1.69588 
this multiplied by 835 
gives 1416.060= 
¿£1416 1 2, the amount required. 
95. To find the Present Value of a sum to be received at the end 
of any number of years. 
Look in Table 4, under the given rate per cent opposite the number 
of years for the present value of £l, which multiplied by the sum will 
give the present value required. 
Example. What is the present value of £835 to be received at the 
end of 12 years, reckoning at 5 per cent compound interest? 
In Table 4, under 5 per cent opposite 12 years, we find .556837 
which multiplied by 835 
gives 464.964= 
£464 19 3, the present value required. 
ANNUITIES AT COMPOUND INTEREST. 
96. To find the amount of an annuity in any number of years. 
In Table 5, under the given rate per cent opposite the number of 
years, find the amount of £l per annum and multiply by the annuity. 
Example. What is the amount of £80 per annum in 12 years, at 4 
per cent compound interest ?
