On the number table of 1-100, we finally reached 50 after we added 72 and subtracted 36 from the original number .What is the original number ?

• 86

• 14

• 48

• 50

• 84

Answer explanation

we perform two operations on x:

1. We add 72 to x.

2. Then, we subtract 36 from the result of that addition.

The final result after these operations is given as 50. Therefore, we can express this mathematically as:

x+72−36=50

Now, let’s simplify the left side of the equation:

x+(72−36)=50x+36=50

Next, we need to isolate x. To do this, we will subtract 36 from both sides of the equation:

x+36−36=50−36x=14

Thus, the original number is 14.

Roy walks 10m to his school and then continues the remaining three-fourths of the whole journey by bus.How far is Roy's School from his house ?

• 134m

• 100m

• 30m

• 40m

• 400m

Answer explanation

This can be expressed mathematically as:

Distance walked+Distance by bus=D

Given that he walks 10 meters and travels three-fourths of D by bus, we can express this as:

10+34D=D

Step 3: Solving for D

To isolate D, we first rearrange the equation:

10=D−34D

This simplifies to:

10=14D

Next, we multiply both sides by 4 to solve for D:

D=40
