Money with Raka = ₹52
Cost of pair of bangles = ₹120
If half price sale is going on then bangles are available in half of the price .
We know how to calculate half of any given number.
Half of ₹120 will be = 120 ÷ 2 = ₹60
Unfortunately Raka has just ₹52 with him that means he is ₹8 short, and can not buy the bangles.
