.The square root of 1.44 can be written as (1.44)1/2. So

(1.44)1/2 = (1.2 × 1.2)1/2

(1.44)1/2 = [(1.2)2]1/2

(1.44)1/2 = (1.2)2/2

(1.44)1/2 = (1.2)1

Thus,

√1.44 = 1.2

Explanation

Given:  

- Current dosage = 340 mg  

- Decrease required = 30% of 340 mg  

Step 1: Find 30% of 340  

30% of 340 = (30/100) × 340 = 102 mg

Step 2: Subtract from original dosage  

340 mg − 102 mg = 238 mg

Explanation

Given:  

6.334 × 10000

Step: Multiply 6334/10000 x 10000  

 = 63,340

Explanation

Let the Breadth be = x

then length be = 3x

Given:

Breadth is 7cm  

If x = 7 cm  

Then,

3x = 3(7)  

= 21cm

Explanation

Given numbers: 8, 13, 25, 43, 11

Step 1: Add the numbers  

8 + 13 + 25 + 43 + 11 = 100

Step 2: Divide by the number of values  

100 ÷ 5 = 20

Explanation

We have to find the Average: 

Day 1 = 116 miles 

Day 2 = 130 miles 

Day 3 = 114 miles 

Average = Sum of terms / No. of terms 

Average = 116 + 130 + 114 / 3

= 360/3 

=120 miles

Explanation

Series: 8, 13, 10, 15, 12, 17, 14, ?

Let’s break it into two alternating patterns:

- 1st, 3rd, 5th, 7th terms: 8, 10, 12, 14 → increasing by 2  

- 2nd, 4th, 6th terms: 13, 15, 17 → increasing by 2

So next (8th) number continues the second pattern:  

17 + 2 = 19

Explanation

(25 x 10)/(5(6-4)2) =?

First, we solve brackets:

⇒ 250/10(2)

⇒ 25/2

Explanation

1/10 = 0.1
