3. There is a series in arithmetic progression, comprising 240 terms. The 47th term and 211th term of the progression are 23 (3/43) and 177 (13/43) respectively. To this series, P terms are added at the beginning and another (P + 17) terms are added at the end such that the entire series is still in arithmetic progression.

9. Arjun went to a market to buy apples, bananas and oranges. He bought an equal number of bananas and oranges and twice as many apples as oranges, thereby spending all the money he had with him. The sum of the prices of 1 apple, 1 banana and 1 orange is Rs.12. Instead, if the cost of each orange was equal to the actual price of an apple, the other prices remaining the same, he would have just been able to buy as many apples and oranges that he actually bought but would have had no money left over to buy any bananas. If he purchased 60 fruits on the whole, find the expenditure he incurred on apples.
