Question

The price of a scooter was rupees 34000 last year. It has increased by 20% this year. What is the price now?

Answer 1

40,800

Explanation:

`\bold{METHOD\ 1:}\\\\\begin{array}{ccc}34,000&-&100\%\\\\x&-&20\%\end{array}\qquad\text{cross multiply}\\\\100x=(34,000)(20)\\\\100x=680,000\qquad\text{divide both sides by 100}\\\\x=(680,000)/(100)\\\\x=6,800\\\\34,000+6,800=40,800`

`\bold{METHOD\ 2:}\\\\p\%=(p)/(100)\\\\\text{The price has increased by 20}\%\\\\100\%+20\%=120\%\\\\120\%=(120)/(100)=1.2\\\\120\%\ of\ 34,000\to1.2\cdot34,000=40,800`
