Question

I want answers of question 10 11 and 12

Answer 1

10. Let sum = p
Rate of Simple Interest = 6%
Time = 3 years

Interest =
$\frac{p \times 6 \times 3}{100}$
Amount =
$p + \frac{p \times 6 \times 3}{100}$
By the Question,
$p + \frac{p \times 6 \times 3}{100} = 4130 \\ or \: \: p + \frac{18p}{100 } = 4130 \\ or \: \: 100p + 18p = 413000 \\ or \: \: 118p = 413000 \\ or \: \: p = \frac{413000}{118}$
Do the others yourself
