Example There are twelve dozen of apples in a basket. Two dozen are added later. Ten apples got spoilt and are removed. The remaining are transferred equally into two baskets. How many apples are there in each? SSC (10+2) 2012
(d) Initially number of apples in basket =12 x 12 = 144
Again, after added two dozen apples number of apples in basket =144 + 12 x 2=168
After ten apples got spoilt number of apples in basket = 168 – 10 = 158
So, after transferred equally into two baskets number of apples in each basket = 158/2 = 79
1. Ali had Rs 320. He spent 3/4th of it to buy a watch. Of the remainder, he used 1/8 th of it to buy a pen. How much money is left? SSC (10 + 2) 2015
(c) After purchasing the watch, remaining amount of Ali
= 320 – 320 x 3/4 = 320 – 80 x 3
