• # question_answer If 60% of K is 30 less than 75% of K, then what is the value of K? A)  500                             B)  300     C)  400                             D)  200

(d): $\frac{60}{100}\times K=\frac{75}{100}\times K-30$ $\Rightarrow 30=\left( \frac{75-60}{100} \right)\times K$ $\Rightarrow \frac{15K}{100}=30\Rightarrow K=200.$
