Explanation

To find the cost price (CP), use the formula:

CP = Selling Price (SP) / (1 + Gain %)

CP = 48 / (1 + 0.20)

CP = 48 / 1.20

CP = 40

Explanation

• To convert a decimal to a percentage, multiply by 100:
  

$0.09\times 100=9\mathrm{\%}$

Explanation

• Calculate 3% of 20:

$3\mathrm{\%}\times 20=\frac{3}{100}\times 20=0.6$

Explanation

• Distribute the 2 across the terms inside the parentheses:
  

$2(x^2+y^2+xy)=2x^2+2y^2+2xy$

Explanation

729 = 27 × 27

√729 = √(27 × 27)

√729 = 27

Explanation

The sequence follows a pattern of adding 7:

102 + 7 = 109

109 + 7 = 116

116 + 7 = 123

123 + 7 = 130

130 + 7 = 137

This is an arithmetic sequence with a common difference of 7.

Explanation

The sequence follows a pattern of dividing by 2:

64 ÷ 2 = 32

32 ÷ 2 = 16

16 ÷ 2 = 8

8 ÷ 2 = 4

This is a geometric sequence with a common ratio of ½.
