Mohit joined a course, fees of which is Rs 100000. His father gave him 30% of actual fees amount while mother gave him 20% of remaining fees. He collected 50% of remaining from his friends. Remaining amount he borrowed from a café owner for which he had to work there where he was getting Rs 2500 per month. For how long he has to work at café? (approximate integral value)

Sure, let's solve the problem step by step.

Step 1: Calculate the amount Mohit's father gave him. Mohit's father gave him 30% of the actual fees amount, which is Rs 100,000. So, the amount given by his father is 30/100 * 100,000 = Rs 30,000.

Step 2: Calculate the remaining fees after his father's contribution. The remaining fees after his father's contribution is Rs 100,000 - Rs 30,000 = Rs 70,000.

Step 3: Calculate the amount Mohit's mother gave him. Mohit's mother gave him 20% of the remaining fees, which is Rs 70,000. So, the amount given by his mother is 20/100 * 70,000 = Rs 14,000.

Step 4: Calculate the remaining fees after his mother's contribution. The remaining fees after his mother's contribution is Rs 70,000 - Rs 14,000 = Rs 56,000.

Step 5: Calculate the amount Mohit collected from his friends. Mohit collected 50% of the remaining fees from his friends. So, the amount collected from his friends is 50/100 * 56,000 = Rs 28,000.

Step 6: Calculate the remaining fees after collecting from friends. The remaining fees after collecting from friends is Rs 56,000 - Rs 28,000 = Rs 28,000.

Step 7: Calculate the number of months Mohit has to work at the café. Mohit borrowed the remaining amount from the café owner, which is Rs 28,000. He was getting Rs 2,500 per month from the café owner. So, the number of months he has to work at the café is Rs 28,000 / Rs 2,500 = 11.2 months.

Since we need to find the approximate integral value, Mohit has to work at the café for approximately 11 months.
