Explanation

15 ÷ 3 = 5

5 + 20 = 25

Explanation

Let's simplify the expression:

5√3 + √12

First, simplify √12:

√12 = √(4 × 3) = √4 × √3 = 2√3

Now add:

5√3 + 2√3 = 7√3

Explanation

The common difference (d) is the difference between consecutive terms:

d = 3 - (-1) = 4

d = 7 - 3 = 4

d = 11 - 7 = 4

The common difference is:

4

Explanation

If the cost of three dozens of apples is Rs. 324, how much do 10 apples cost?

3 Dozens = 12x3 =36

One apple Price = 324/36 = 9

10 Apples Price = 10x 9 = 90

Explanation

X + Y = 10

X + Y = 10

Double X = 20

Divide 20 by 2 = 10

Explanation

Total admissions = 1250

Graphic designing = 400

Painting = 200

Calligraphy = 500

Total for these three = 400 + 200 + 500 = 1100

Admissions for baking = 1250 - 1100 = 150

Fraction for baking = 150 / 1250

= 3 / 25

Explanation

Multiply: 0.4 x 710 =​284

Explanation

The number 9000 (without a decimal point) has only 1 significant figure.
