Answer» let the two numbers are X and ythen,x/y = 3/5x=(3y) /5. ......(1)also,(x+10)/(y+10) = 5/77(x+10)=5(y+10)7x = 5y+50-70=5y-20put the value of x from EQ. (1)7(3y/5) =5y - 2021y =25y - 10025y-21y = 100y = 100/4 y =25put the value of y in eq.(1)x = (3×25)/5 x=15hence , the numbers are 15 and 25Step-by-step explanation: |
