Answer 1

Answer:

Rs 1800

Step-by-step explanation:

in a certain time rupees 1200 becomes 1560 at 10% per annum simple interest and principal amount that will become rupees 2232 at 8% per annum in the same time is​

P = Rs 1200

R = 10 % per annum

Simple interest = 1560 - 1200 = Rs 360

T = time in Years

Simple interest  = P * R * T  /100

=> 360 = 1200 * 10 * T/100

=> T = 3

P = ?

R = 8 % per annum

T = 3

Simple interest = 2232 - P

=> 2232 - P = P * 8 * 3 /100

=>  2232 - P = 0.24P

=> 2232 = 1.24P

=> P = 1800

Rs 1800 will become Rs 2232 at 8% per annum in 3 Years
