This is a word problem of basic operations, multiply and subtracting. To solve this type of problem read the question carefully and just follow the steps.

**Step1:**

Question starts with, if you triple 4

Triple means 3

If you triple 4 means we have to multiply 3 by 4

3 * 4 = 12

**Step2:**

Now subtract 2 each day

Subtract 2 from 12 and then subtract 2 every time from the result until we have zero

On first day 12 – 2 = 10

On second day 10 -2 = 8

On third day 8 -2 = 6

On fourth day 6-2 = 4

On fifth day 4 -2 = 2

On Sixth day 2 -2 = 0

We got Zero on Sixth day.

It means, if we triple 4 and subtract 2 each day, then 6 days until we have zero.

Or we can solve this problem like this also

**Step1:**

Triple means 3

If you triple 4 means we have to multiply 3 by 4

3 * 4 = 12

**Step2:**

Subtract 2 each day, how many days until you have zero.

Divide 12 by 2

12 2 = 6

So, the answer is 6 days.

It means if we triple 4 and subtract 2 each day then 6 days until we will have zero.

**Basic instructions to solve word problems involving mathematical operations**

**Word problems involving basic operations adding, subtracting, multiplication, division and the words like double/twice, triple/thrice, four times etc.**

Double/Twice means we have to multiply by 2

Triple/Thrice means we have to multiply by 3

Four times means we have to multiply by 4

Five times means we have to multiply by 5

And so on.

Half part means we have to divide by 2

Third part means we have to divide by 3

And so on.

**More Examples**

**Q.1 If you double 6 and subtract 3 each day, how many days until you have zero?**

**Step1:**

This is a word problem of basic operations, multiply and subtracting. To solve this type of problem, read the question carefully and just follows the steps.

Question starts with, if we double 6

Double means 2

If you double 6 means we have to multiply 2 by 6

2 * 6 = 12

**Step2:**

Now subtract 3 each day

Subtract 3 from 12 and then subtract 3 every time from the result until we have zero

On first day 12 – 3 = 9

On second day 9 -3 = 6

On third day 6 -3 = 3

On fourth day 3-3 = 0

We got Zero on fourth day.

It means if we double 6 and subtract 3 each day then 4 days until we have zero.

Or we can solve this problem like this also,

**Step1:**

Double means 2

If you double 6 means we have to multiply 2 by 6

2 * 6 = 12

**Step2:**

Subtract 3 each day, how many days until we have zero.

Divide 12 by 3

12 3 = 4

So, the answer is 4 days.

It means, if we double 6 and subtract 3 each day then 4 days until we have zero.

**Q.2 If you triple 8 and add 4 each day, how many days until you have 60?**

**Step1:**

This is a word problem of basic operations, multiply and subtracting. To solve this type of problem read the question carefully and just follows the steps.

Question starts with, if you triple 8

triple means 3

If you triple 3 means we have to multiply 3 by 8

3 * 8 = 24

**Step2:**

Now add 4 each day

Add 4 to 24 and then add 4 every time from the result until we have 60

On first day 24 + 4 = 28

On second day 28 + 4 = 32

On third day 32 + 4 = 36

On fourth day 36 + 4 = 40

On fifth day 40 + 4 = 44

On sixth 44 + 4 = 48

On seventh day 48+ 4 = 52

On eighth day 52 + 4 = 56

On ninth day 56 + 4 = 60

We got 60 on ninth day.

It means if we triple 8 and add 4 each day then 9 days until we have 60.

Or we can solve this problem like this also,

**Step1:**

triple means 3

If you triple 3 means we have to multiply 3 by 8

3 * 8 = 24

**Step2:**

Add 4 each day, how many days until we have 60.

Divide 60 by 4

60 4 = 15

Divide 24 by 4

24 4 = 6

Subtract the result of 24 divided by 4 from the result of 60 divided by 4.

Subtract 6 from 15

15 – 6 = 9

So, the answer is 9 days.

It means if we triple 8 and add 4 each day then 9 days until we have 60.
