105×106 = (100+5)(100+6) = 10000 + 500 + 600 + 30 = 11030

The answer is 100/9 or 11(1/9)

Sum of first 9 prime numbers:2+3+5+7+11+13+17+19+23= 100

Average = 100/9

let the ratio be xso ratio are x/5 and x/6Therefore,x/6 + x/5 = 88011x/30 = 880x = (880×30)/11 = 80 × 30x = 2400

So, cost are x/6 = 2400/6 = 400x/5 = 2400/5 = 480

Continued proportion : Three numbers ‘a’, ‘b’ and ‘c’ are said to be continued proportion if a, b and c are in proportion. Thus, if a, b and c are in continued-proportion, then a,b,b,c are in proportion, that means Product of extremes = Product of means ⇒ a x c = b x b ⇒ a x c = b 2 Continued-proportion is also known as mean proportional .If ‘b’ is a mean proportional between a and c then b 2 = ac.

Examples : 1)Find the mean proportional between 9 and 25.Solution : Let x be the mean proportional between 9 and 25.⇒ x 2 = 9 x 25 ⇒ x 2 = 225 ⇒ x = 15 Hence, the mean proportional between 9 and 25 is 15.

a(n) = 4n + 1

a(3) = 4 × 3 + 1

a(3) = 12 + 1 = 13

two consecutive number be 2x + 1 and 2x + 3 so,according to question2x + 1 + 2x + 3 = 284x + 4 = 284x = 24x = 6so number are2x + 1 = 2× 6 + 1 = 132x + 3 = 2× 6 + 3 = 15

Given Sin A = sqroot(3)/2 = P/H

To find B use pythagoras theoramB*B = 2*2 - sqroot(3)*sqroot(3)B*B = 4 - 3 = 1B = 1

Cot A = B/P = 1/sqroot(3)

Thus, 2Cot^2 A - 1 = 2*1/3 - 1 = 2/3 - 1= - 1/3

a) let fourth Proportional be x

so,

24/4 = 12/x

6 = 12/x

x = 12/6

x = 2

b) let fourth Proportional be x

10/2.5 = 1.2/x

100/25 = 1.2/x

x = 1.2/4

x = 0.3

3p+7=193p = 19-73p = 12p = 12/3p= 4is the correct answer
