Question

If 60% of K is 30 less than 75% of K , find value of K.​

Answer 1

k × 60/100 = k × 75/100 -30

60k/100 = 75k/100 -30

60k = 75k -3000-15k = -3000

k = -3000/ -15

k = 200

Hope it helps you ☺️

Answer 2

If 60% of k is 30 less than 75% of k,

we know that 30 is equal to (75–60 = 15)% of k.

$\frac{15}{100} k = 30 \\ 15k = 30 \times 100 \\ k = \frac{30}{15} \times 100 = 200$

➳Value of K = 200

$checking \: our \: work \: \\ \frac{60}{100} \times 200 = 120 \\ \frac{75}{100} \times 200 = 150 \\ 150 - 120 = 30 \\its \: means \: our \: answer \: is \: correct \: = 200$
