The correct option is A ₹10
Total money spent = 40 + 20 + 20 + 10
= ₹90
Money spent on apples = ₹40
If we spend ₹10 more on apple
Money spent on apples = ₹50
And Now, the total money spent
= ₹90 + ₹10
= ₹100
Money spent on apple will be half of the total money spent
= 12 × ₹100
= ₹50
We need to spend ₹10 more on apples.
