Ratio of area = a²/ ?(3/4) a²
= 4/?3 = 4:?3

? log tan 45 = log 1 = 0
Hence, Whole Expression = (something) x zero

Prime number less than 40 are 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37
? The number of all prime numbers less than 40 = 12.

(1/5 )^3a = 0.008 = 8/1000 = 1/125 = (1/5 )³
Apply the Algebra Law and Solve the equation.
? 3a = 3
? a = 1
? ( 0.25 )^a = ( 0.25 )¹ = 0.25

Let CP of the article be ? N
Then, SP = 110% of x = 1.1N
If SP be double i.e., 2.2N, then
Profit per cent= [(2.2N - N)/ N] x 100% = 120%

Curved surface area = ?rl
= (22/7 x 6 x 28) cm²
= 528 cm²

Number of boy = ( 2140 - 1200 ) = 940
? Boys : Girls = 940 : 1200 = 47 : 60
