Question

Calculate the compound interest on Rs 7500 in 2 years when the rate of interest on successive years is 8% and 10% respectively

Answer 1

Step-by-step explanation:

P= Rs. 7500

P= Rs. 7500T= 2yrs

P= Rs. 7500T= 2yrsr1= 8%

P= Rs. 7500T= 2yrsr1= 8%r2= 10%

P= Rs. 7500T= 2yrsr1= 8%r2= 10%A =P(1+r1/100)(1+r2/100)

P= Rs. 7500T= 2yrsr1= 8%r2= 10%A =P(1+r1/100)(1+r2/100) =7500(1+8/100)(1+10/100)

P= Rs. 7500T= 2yrsr1= 8%r2= 10%A =P(1+r1/100)(1+r2/100) =7500(1+8/100)(1+10/100)=7500×( 1+4/50)(1+1/10)

P= Rs. 7500T= 2yrsr1= 8%r2= 10%A =P(1+r1/100)(1+r2/100) =7500(1+8/100)(1+10/100)=7500×( 1+4/50)(1+1/10)=7500×(54/50)(11/10)

P= Rs. 7500T= 2yrsr1= 8%r2= 10%A =P(1+r1/100)(1+r2/100) =7500(1+8/100)(1+10/100)=7500×( 1+4/50)(1+1/10)=7500×(54/50)(11/10)=Rs 8910

CI = A-P

=8910-7500

= Rs. 1410
