Question

1. What number must be subtracted from each of 7, 8, 11 and 14, so
that the remainders are proportional.​

Answer 1

HELLO MATE:-

let the number = x

so

x-7, x-8, x-11 and x-14 are proportional

that means

x-7: x-8 :: x-11: x-14

then

$\frac{x - 7}{x - 8} = \frac{x - 11}{x - 14}$

$(x - 7)(x - 14) = (x - 8)(x - 11)$

${x}^{2} - 21 x + 98 = {x }^{2} - 19x + 88$

$- 2x = - 10$

$x = 5$
