Correct Answer - Option 1 : Rs.560
Calculation:
Let the price of rice in April be Rs. x
And the price of wheat in April be Rs. y
According to the question
The price in May will be 1.2x of rice and 1.12y of wheat
Now quantity bought in April = 450/x
As per the question, extra money spend on rice in May
⇒ (450/x) × 0.2x = Rs. 90
So extra money spend on wheat
⇒ 150 – 90 = Rs. 60
Let the amount spent on wheat be k in April then,
⇒ (k/y) × 0.12y = 60
⇒ k = Rs. 500
So money spent on wheat in May
⇒ 500 + 60 = Rs. 560
∴ The money spends on the wheat in May is Rs. 560.
