Hi can someone help me with this maths question…


During a camp, the pupils were divided into 2 groups, A and B. 3/7 of the pupils in Group A were boys while 3/5 of the pupils in Group B were boys. It was found that 1/3 of the boys and 3/8 of the girls in Group A could swim whereas 7/9 of the boys and 5/6 of the girls in Group B could swim. If the total number of boys who could swim was 534 and the total number of girls who could swim was 449, find the total number of pupils in the camp.
