Answer» Answer: Let the THREE NUMBERS be = x, y and z According to the given question :- x = 3y ...(1) z = 5x ...(2) We can also find that :- 3y = \TT{\frac{z}{5}}\\ y = \tt{\frac{z}{15}}\\ ...(3) Average = 57 =》 \SF{\frac{x+y+z}{3} = 57}\\ Replace the values by (1),(2) and (3) =》 \sf{\frac{3y+y+15y}{3} = 57}\\ =》 \sf{\frac{19y}{3} = 57}\\ =》 \sf{y = 9} \sf{x = 3y = 27} \sf{z = 5x = 135} |
