Rahul's Mathematics test had 75 problems, 10 arithmetic, 30 algebra, 35 geometry problems.
Although he answered 74% of arithmetic, 40% of arithmetic and 60% of geometry problems correctly,
still he got less than 58% problems right. How many more questions he would have to answer more to get
passed
Answer/Solution
3
Steps/Work
Explanation:
Number of questions attempted correctly = (70% of 10 + 40% of 30 + 60% of 35)
= 7 + 12 + 21 = 40.
Questions to be answered correctly for 58% = 58% of total quations
= 58 % of 74 = 43.
He would have to answer 43 - 40 = 3
Answer: Option A
