Question

if rupees 15000 amounts to rupees 20400 I 9/2 years how much will rupees 6500 to in 13/4 years at the same rate of simple interest per annum​

​

Answer 1

Answer:

Let interest is X % / annum.

so,

$20400 - 15000 = \frac{15000 \times \frac{9}{2} \times x}{100}$

$75 \times 9x = 5400$

$x = \frac{5400}{75 \times 9} = \frac{600}{75} = 8\%$

now, ₹6500 in 13/4 yr. become

$6500 + \frac{6500 \times 8 \times \frac{13}{4} }{100} = 6500 + 65 \times 26 = 6500 + 1690 = 8190$
