Question

sunilearns 10% more than shailesh and shailesh earns 20% more than swami. if swami earns 3200 less than sunil find the earnings of each

Answer 1

let's assume the earnings of Sunil are x and earnings of Shailesh are y and earnings of Swami are z it is given that x=y+10%y and y=z+20%z and z=x-3200 take them as equation 1,2,3 respectively from equation 2 we get y=1.2z now substitute equation 3 in 2 we get y=1.2(x-3200) take it as equation 4 now we get x=1.1y from equation 1 substitute equation 1 in 4 we get y=1.2(1.1y-3200)after simplifying this equation we get y=12000 from this we get x=1.1(12000)=13200 and z=x-3200=10000 therefore earnings of Sunil, Shailesh,Swami are 13200,12000,10000 respectively
