(A):

From the graph, we know that – Money saved by Akansha = Rs. 350
Money saved by Mohit = Rs. 200
Twice Mohit’s money = 200 x 2 = Rs. 400
That means, Akansha needs to save another 400 – 350 = Rs. 50 so that
she has twice as much money as Mohit.
So, option A is the correct answer.

(D):

74 x 43 = 3182
Now, 
A) 70 x 43 + 4 x 43 = 3182

Therefore, 74 x 43 is not equal to 72 x 43 x 2.
