the same rate of interest and received 2,200 in all from both of them as interest. Find the
rate of interest per year.​

Answer 1

Answer:

The rate of interest per annum is 10%

Step-by-step explanation:

Let the rate of interest per annum be x%

P*r*t/100 + p*r*t/100 = 2,200

5,000*x*2/100 + 3,000*x*4/100 = 2,200 50*x*2 + 30*x*4 = 2,200

100x + 120x = 2,200

220x = 2,200

x = 2,200/220 = 10%(answer).
