Which of the following statements is INCORRECT?

A Kusum buys some chocolates at the rate of ₹ 10 per chocolate. She also buys an equal number of candies at the rate of ₹ 5 per candy. She makes a 20% profit on chocolates and 8% profit on candies. At the end of the day, all chocolates and candies are sold out and her profit is ₹ 240. Therefore, Kusum buys 100 chocolates.
B A carpenter charged ₹ 2500 for making a bed. The cost of materials used is ₹ 1100 and the labour charges are ₹ 200/hr. So, the carpenter will work for 7 hours.
C On dividing ₹ 200 between A and B such that twice of A's share is less than 3 times B's share by 200. So, B's share is ₹ 120.
D Madhulika thought of a number, double it and added 20 to it. On dividing the resulting number by 25, she gets 4. Hence, the required number is 45.
