Option A
Step-by-step explanation:
Given that Crisply clover is a popular vegetarian restaurant.
It introduced a new menu
The new menu had 20% more dishes than the previous menu
Let the dish as per previous menu = D
Now added for new dish 20% = (20/100)D
Simplify to get 1/5 D
Hence new menu has = D+(20/100)D
= D+1/5 D
Thus we find that option A is the right answer,
