As part of the 'Learning Journey' program, 73 pupils travelled on two buses, one air-conditioned and one non-air-conditioned, to the Singapore Discovery Centre. Three-fifths of the pupils on the air-conditioned has wee girls. There were 17 boys in the non-at, conditioned bus. The number of girls on the two buses were equal. How many pupils wee there on the air-conditioned bus?

Question

As part of the 'Learning Journey' program, 73 pupils travelled on two buses, one air-conditioned and one non-air-conditioned, to the Singapore Discovery Centre. Three-fifths of the pupils on the air-conditioned has wee girls. There were 17 boys in the non-at, conditioned bus. The number of girls on the two buses were equal. How many pupils wee there on the air-conditioned bus?

Answer 1

To find the number of pupils on the air-conditioned bus, we need to gather the information provided in the question and use basic arithmetic.

Let's break down the information given:

1. The total number of pupils on both buses is 73.
2. Three-fifths (3/5) of the pupils on the air-conditioned bus are girls.
3. There were 17 boys on the non-air-conditioned bus.
4. The number of girls on both buses is equal.

Let's use this information to find the number of pupils on the air-conditioned bus:

Step 1: Subtract the number of boys on the non-air-conditioned bus from the total number of pupils to find the number of girls on both buses.
Total number of girls on both buses = Total number of pupils - Number of boys on the non-air-conditioned bus
Total number of girls on both buses = 73 - 17
Total number of girls on both buses = 56

Step 2: Since the number of girls on the air-conditioned bus is three-fifths (3/5) of the total number of pupils on that bus, we can set up an equation to solve for the number of pupils on the air-conditioned bus.
Number of girls on the air-conditioned bus = (3/5) * Number of pupils on the air-conditioned bus

Step 3: We know that the number of girls on both buses is equal, so we can equate the two equations:
Total number of girls on both buses = Number of girls on the air-conditioned bus
56 = (3/5) * Number of pupils on the air-conditioned bus

Step 4: Solve the equation for the number of pupils on the air-conditioned bus:
Number of pupils on the air-conditioned bus = (56 * 5) / 3
Number of pupils on the air-conditioned bus = 280 / 3
Number of pupils on the air-conditioned bus ≈ 93.33

Since we cannot have a fraction of a pupil, we round the answer down to the nearest whole number. Therefore, there were approximately 93 pupils on the air-conditioned bus.
