CAT 2017 – Quantitative Aptitude – Arithmetic – Profit and Loss

Let Retail Price = MP

Cost Price = CP

When a discount of 15% is given,

[(0.85CP â€“ CP)/CP] *100 = 2

So, 85 * MP = 102 * CP

Let us take SP = xMP

So, [(xMP-CP)/CP] * 100 = 20.

On calculating, we get x = 100

So, we should sell at Retail Price to get a profit of 20%.
