Expression: 15% of 1.5 + 0.15 ÷ 0.1 + 0.01 of 1.1 × 0.5 + 2.5 × 25
Formula Used:
1. a% of b = a/100 × b
2. Division and multiplication operations follow BODMAS/BIDMAS rules.
Calculation:
15% of 1.5
⇒ 15/100 × 15/10
⇒ 0.225
0.01 of 1.1 × 0.5
⇒ 1/100 × 11/10 × 5/10
⇒ 0.0055
2.5 × 25
⇒ 25/10 × 25
⇒ 62.5
Now, summing all the parts together:
0.225 + 1.5 + 0.0055 + 62.5
⇒ 0.225 + 1.5 = 1.725
⇒ 1.725 + 0.0055 = 1.7305
⇒ 1.7305 + 62.5 = 64.2305
The correct answer is option 4.
