उत्तर
Here principal P = ₹ 46900
Time n = 2 years
Amount A = ₹ 53466
Let r be the rate of interest per year
Interest I = `"Pnr"/100`
A = P + I
53466 = 46900 + `(46900 xx 2 xx "r")/100`
53466 – 46900 = `(46900 xx 2 xx "r")/100`
6566 = 469 × 2 × r
r = `6566/(2 xx 469)%`
= 7%
Rate of interest = 7% per year
