Question

Two fifth of a number subtracted from three fourth of it gives 56 find the number

Answer 1

Answer:

let the number be X

$= > \frac{3x}{4} - \frac{2x}{5} = 56 \\ = > \frac{15x - 8x}{20} = 56 \\ = > 7x = 56 \times 20 \\ = > x = \frac{56 \times 20}{7} \\ = > x = 8 \times 20 \\ = > x = 160$

the number is 160

Answer 2

Answer:

$let \: the \: number \: be \: x \\ \frac{3}{4} \times x - \frac{2}{5} \times x = 56 \\ \frac{-8x +15x}{20} = 56 \\ \frac{ 7x}{20} = 56 \\ x = \frac{20 \times 56}{7} = 160$

the no. is ,160
