c) 450 m

d) 580 m

10) Find the value of (sec 52.5o cosec 7.5o).

a) 4(√2 + 1)

b) 4(√2 + √3)

c) 2(4 – √2)

d) None of these

We know that, x3 + y3 + z3 – 3xyz = (x + y + z) × (x2 + y2 + z2 – xy – yz – zx)

As, p + q + r = 0

So, using the above identity,

p+ q3 + r3 = 3pqr

p2 / 3qr + q2 / 3pr + r2 / 3pq = 1

{(p2 / qr) + (q2 / pr) + (r2 / pq)} / 3 = 1

By taking the square root 2 by the divide method, the number up to eight digits is 1.41421356.

Thus, option A is correct.

Selling price = Cost price [(100 – Discount %)/100]

According to question,

Selling price=Rs.499

Discount%=50%

499 = Cost price [(100-50)]/100

Cost price = (499×100)/50 = 499×2 = Rs.998

Given data- 26, 46, 59, 88, 46, 55, 66, 13, 26, 60, 43, 61

Maximum score of 26 is 2 times and maximum score of 46 is 2 times.

Area of the base = l × b = 42 × x

42 × x = 1449 / 1.5

So, x = 23 cm

According to Question –

That is, both metals have to be mixed in the ratio 3 : 5

The share of A, B and C = 7: 8: 9

The Period ratio = 2: 2:3

Investment * Period = Ratio of share of profit

Investment ratio

= (7/2) : (8/2) : (9/3) = (7/2) : 4 : 3

= > 7: 8 : 6

Suppose another mobile is sold at x% profit

According to Question,

2500 × (100+5)/100 + 2500 × (100+x)/100 = 5000 × (100+20)/100

25 × 105 + 25 (100 + x) = 50 × 120

2625 + 2500 + 25x = 6000

25x = 6000 – 5125

25x = 875

x = 35%

Neeraj  : Pankaj  = 2000 : 1900

Suraj  : Neeraj  = 2000 : 1800

Suraj/Pankaj  = Suraj/Neeraj  × Neeraj/Pankaj

= 2000/1800 × 2000/1900 = 2000/1710

∴ Suraj can give to Pankaj, a start of (2000 –  1710) m = 290 m
