Q: Mr. Desmond bought three times as many toys for his younger son as he bought for his elder son. If the elder son received 60 toys, how many toys did Mr Desmond buy?
A: The younger son received three times as many toys as the elder son, which is 3 * 60 = 180 toys. Since he bought the toys together, he purchased 180 + 60 = 240 toys. The answer is 240.

Q: Mrs. Young buys a 300 piece puzzle set for her three sons. She divides the pieces evenly to the three boys. Reyn can place 25 pieces into the puzzle picture. Rhys places twice as much as Reyn. Rory places three times as much as Reyn. Altogether, how many puzzle pieces are still left to be placed?
A: Each son receives 300 / 3 = 100 pieces. Rhys places 25 x 2 = 50 pieces. Rory places 25 x 3 = 75 pieces. All three boys place 25 + 50 + 75 = 150 pieces. The boys have not placed 300 - 150 = 150 pieces. The answer is 150.

Q: There are 3414 yellow balloons and there are 1762 more black balloons than yellow balloons. If the balloons will be evenly divided among 10 schools, how many balloons will one school receive?
A:
Black balloons: 3414 + 1762 = 5176. Total balloons: 3414 + 5176 = 8590. 8590 / 10 = 859. Each school will receive 859 balloons. The answer is 859.
