Here is a P6 question. (By right, P5 can try too.)
“A tour group spent a total amount of $896 for cable car tickets to Sentosa. In the group, the ratio of the number of adult to the number of senior citizens to the number of children was 3 : 2 : 5. The ratio of the amount spent on the senior citizen to the amount spent on the children was 3 : 5. The amount spent on the senior citizens was half the amount spent on the adults.
Given that the price of a child’s ticket was $16, find the total number of people in the tour group.”
