Question

if rupees 1200 amounts to rupees 1740 in 5 years find the sum that will amounts to rupees 2720 and four years at the same rate of interest per annum​

Answer 1

Answer:

Step-by-step explanation:

                                        P =1200 T=5 YEARS R= ?

                       AMOUNT =1740 INTEREST=540

           INTEREST= PRT÷100

                                    540=1200.5.R÷100

              R=9 percent

                           New amount = 2720

             Rate =9 percent

                                     Time= 4 year

            Let P=x

Therefore interest = 2720-x

Interest= PRT÷100

2720-x= x.9.4

100 (2720-x)= 36x

X= 2000

Therefore fixed amount is                                   2000Rs
