(a) 3.2%
(b) 22%
(c) 20.8%
(d) 8%

Answer 1

Radhika bought a car for Rs 250000
$\therefore$ Cost price of a car = Rs 250000
Its price decreased next year for 10%.
So, price became $=250000-\frac{10}{100}\times 250000$
= 250000 - 25000 = Rs 225000
Further next year, its price decreased by 12%, then price will be
$=225000-225000\times \frac{12}{100}$
= 225000 - 27000 = Rs 198000
In two years, overall decrease per cent $=\frac{250000-198000}{250000}\times 100$
$=\frac{52000}{250000}\times 100=\frac{520}{25}=20.8\%$
