Answer 1

Answer:

8

Step-by-step explanation:

SP of 12 marbles = Re.1, loss = 20%

Therefore, CP of 12 marbles

= Rs. 10.8=Rs.1.25

Now, SP of 12 marbles at a gain of 20%

CP×1.2=1.25×1.2

= Rs.1.5

It means in order to gain 20% he should sell 12 marbles for Rs.1.5

i.e. For Rs.1, he should sell 121.5 = 8 marbles
