Question

Rani has 160 DVDs 35 % of her DVDs are thrillers . 2/5 of her DVDs are comedies . The rest of her DVDs are science fiction . How many science fiction DVDs does Rani have ?

Answer 1

Answer: 40

Explanation:

Number of DVDs = 160

Thrillers = 35%

Comedies = 2/5 = 40%

Science fiction = 100 - (35 + 40) = 100 - 75 = 25%

The number of science fiction DVDs that Rani has will be:

= 25% × 160

= 25/100 × 160

= 40
