Question

In a colony, there are $2500$ houses. Out of which, $300$ are vacant. How many houses are occupied?

Answer 1

Total number of houses in a colony $=2500$

Number of Vacant colony $=300$

So, Number of occupied colony $=$$ThH\mathrm{T}\mathrm{O}2500-300$

Step 1: Subtract the ones

First subtract ones $0-0=0$,

Write $0$ under ones column

Step 2: Subtract the tens

Next subtract tens $0-0=0$,

Write $0$ under tens column

Step 3: subtract the hundreds

Next subtract hundreds $5-3=2$,

Write $2$ under hundreds column

Step 4 : Subtract the thousands

Next subtract thousands $2-0=2$

Write $2$under thousands column

So we get,

$ThH\mathrm{T}\mathrm{O}2500-3002200$

Hence, the required solution is $2200$
