There are 10 cards numbered 1 to 10. There are three second standard children Ram, Bilal and Cynthia. The teacher selects 3 cards from the 10 cards without seeing the numbers. She distributes the cards to the children one to each. After the children note down the numbers on the cards she collects them back. She repeats the same process two more times, so each child now has 3 numbers noted down. The teacher asks them to add the numbers and tell her the sums obtained. They told her the sums were 10, 14, 15, but Ram received the same card three times. Bilal and Cynthia received all cards different. What numbered cards did each receive?
