Correct Answer - Option 1 : Rs. 1250
Given:
Money spent on rice = 20%
Money left = Rs. 400
Concept Used:
Total percentage is 100%.
Calculations:
Let the total money that Alisha had be Rs. x.
Money spent on rice = 20%
⇒ Remaining money = (100 - 20)% = 80%
Money spent on cooking oils = 25% of 80%
Similarly, Money spent on other essential items = 35% of 80%
⇒ Total money spent = (25% + 35%) of 80%
⇒ Total money spent = 60% of 80%
Remaining money = (100 - 60)% of 80%
⇒ Remaining money = 40% of 80% of Rs. x
Now, 40% of 80% of Rs. x = Rs. 400
⇒ x = Rs. 400 × (100/40) × (100/80)
⇒ x = Rs. 1250
∴ The total amount of money that Alisha had is Rs. 1250.
