Two numbers are in ratio of 7:10 and if the sum of the numbers is 119. Find the difference of the numbers.
Answer & explanation
Correct answer: option 2
The correct answer is Option 2: 21
Step 1: Let the numbers be
7x and 10x
Step 2: Use the sum
7x + 10x = 119
17x = 119
x = 119 / 17 = 7
Step 3: Find the numbers
7x = 7 × 7 = 49
10x = 10 × 7 = 70
Step 4: Find the difference
70 − 49 = 21
