Question

When 35 is subtracted from a number , it reduces to 80% what is four fifth of that number ?

Answer 1

Your answer is :-


Let, the number be x

So, we subtract 35 from x it reduce 80%

Equation is :-

x - 35 = 80/100×x

=> x - 35 = 4x/5

=> x = 175


Now , 4/5 of 175 is 140

Answer 2

$\textbf {\huge {\underline{Hey there!}}}$

$<b>We are given, 35 when subtracted from a number, reduces to its 80 %.$


Therefore,


Let the number be x


⇒ x - 35 = 80 / 100 × x


⇒ x - 35 = 80x / 100


⇒ 100x - 3500 = 80x


⇒ 100x - 80x = 3500


⇒ 20x = 3500


⇒ x = 175


Now, we are asked to find the four-fifth of that number i.e x


⇒ 4 / 5 × x = 4 / 5 × 175


⇒ 4x / 5 = 35 × 4


⇒ 4x / 5 = 140
