Question

there are 40 persons in a Bus some with rupees 3 ticket and remaining with rupees 10 ticket the total collection from the passenger is rupees 295 find how many passenger have ticket worth rupees 3

Answer 1

let 3 rupees person be x
cost of them would be 3x
10 rupees person are remaining which means it would be 40 - x
so equation is
$3x + 10(40 - x) = 295 \\ 3x + 400 - 10x = 295 \\ - 7x = 295 - 400 \\ - 7x = - 105 \\ 7x = 105 \\ x = 105 \div 7 \\ x = 15$
3 rupees customer are 15
10 rupees.coustmer = 40-15 = 25
