Question : 54 of 150

Marks: +1, -0

(10 tens + 11 hundreds + 12 ones) equals

Solution:

Concept:

Each digit's place value matters: 1 ten = 10, 1 hundred = 100, and 1 one = 1. Multiply the given count by the respective place value.

Explanation:

Start with 10 tens. That is

10 \times 10 = 100

Next, 11 hundreds. That is

11 \times 100 = 1100

Then, 12 ones. That is

12 \times 1 = 12

Add all the results:

100 + 1100 + 12 = 1212

No further simplification is needed; it matches option D.

Answer:

D. 1212
