Rahul and Faisal went out for dinner. Rahul paid one-fourth of what Faisal had paid. How much did Faisal pay, out of the total bill of Rs.790?

Correct option is D

1. Define Variables:
· Let 'x' be the amount Faisal paid.
· Rahul paid one-fourth of what Faisal paid, so Rahul paid (1/4)x.
2. Total Bill:
· The total bill was Rs. 790.
· So, the sum of what Rahul and Faisal paid is x + (1/4)x = 790.
3. Solve for x (Faisal's payment):
· Combine the terms: (4/4)x + (1/4)x = 790
· (5/4)x = 790
· Multiply both sides by 4/5: x = 790 x (4/5)
· x = (790 x 4) / 5
· x = 3160 / 5
· x = 632
Therefore, Faisal paid Rs. 632.
