Question 1
1 / -0

The ratio of two numbers is 4 : 5. If the first number is increased by 25 and the second is decreased by 5, then the terms of the ratio become the same. Find the two original numbers.

A
40 and 90

B
80 and 100

C
100 and 120

D
120 and 150

Solution

Let the original numbers be 4x and 5x.
Terms of the ratio become the same, therefore the numbers become equal.
4x + 25 = 5x - 5
5x - 4x = 25 + 5
x = 30

So, the numbers are:
4x = 4 × 30 = 120
5x = 5 × 30 = 150
Question 2
1 / -0

In an exam, the passing score is 40%. A student scores 30% and fails by 30 marks. Find the total marks of the exam.

A
100

B
200

C
300

D
150

Solution

Passing score is 40%, and the student scores 30% and fails by 30 marks.
So, 40% - 30% = 10%
10% of total marks = 30
100% of total marks = 30 × 10 = 300 marks
