Question

Sum of a number and 6% of itself is 42.4 find a number

Answer 1

hi friend!

let the number be x
6% of number = 6/100 × x = 6x/100 = 3x/50

Sum of the number and 6% of itself = 42.4
x + (3x/50) = 42.4
(50x+3x)/50 = 42.4
53x = 42.4 × 50
53x = 2120
x = 2120/53
x = 40

therefore, the number is 40

hope it helps

Answer 2

let the number be x
x+6/100×x=42.4
(100x+6x)/100=42.4
106x=42.4×100
x=4240/106
x=40.
