Given : Ram lent 3 persons A, B and C at the rate of 15%,12% and 10% respectively. he gets 960 at the end of year then find the amount lent to A?
To Find : amount lent to A?
Solution:
SI = P * R * T /100
Question lakes lot of details
A * 15*1/100 + B*12*1/100 + C*10*1/100 = 960
=> A(0.15) + B(0.12) + C(0.1) = 960
One equation 3 Variables:
Not Possible to solve
Assume Amount lent Equal to Each person = P
Then interest = P( 15 + 12 + 10) * 1/100 = 960
=> P = 96000/37
=> P = 2,594.6
Amount lent to each person = 2,594.6
Amount lent to A = 2,594.6
if interest earned equaled from each
= 960/3 = 320
=> P * 15 * 1 / 100 = 320
=> P = 2,133.33
Amount lent to A = 2133.33
