Answer:
The larger number is 54
Step-by-step explanation:
► To find the two numbers
Ratio Given = 1 : 2
Let the two numbers be '1x' and '2x'
According to the Question:
→ 1x + 2x = 81
⇒ 3x = 81
- By transposing 3 from L.H.S. to R.H.S, the sign of operation changes from multiplication to division, and we get:
⇒ x = 81/3
∴ x = 27
If x = 27, then:
1x = 27 × 1 = 27
2x = 27 × 2 = 54
∴ The Ratio actually is 27 : 54 and the larger number is 54
