8.

gurdeep lost 20% by selling a bicycle for rs 1536. what percent should i gain by selling it for rs2040?

Answer»

Loss = 20%

LET CP = x

So SP is 80 % of CP

80/100 x = 1536

x = 15360 / 8

x = 1920

CP = 1920

New SP = 2040

Profit = 2040 - 1920 = 120

Profit % = 120/1920 * 100 = 1/16 * 100 = 25/4 = 6.25%

28.

Find integration of 5^5^5^x×5^5^x×5^x

Answer»

5(5X + 5-X) = 26

let 5x = y so 5-x = 1/y

5(y + 1/y) = 26

5( (y2 + 1)/y ) = 26

(y2 + 1)/y = 26/5

so 5x = 5

x = 1

40.	Find gcd of 4999 and 1109 and also express it in 4999m +1109n
Answer» Given:- Two prime numbers 4999 and 1109. To Find:- Find the gcd of 4999 and 1109 and also express it in 4999m+1109n. Solution:- According to question we have to find the gcd of 4999 and 1109. Since, 4999 and 1109 both the numbers are prime numbers which can't be further break into other smaller prime numbers. Therefore, here, we USE Euclid's Algorithm to find the gcd of 4999 and 1109:- So, using Euclid's Algorithm , we have Step.1 :- divide the larger number by the smaller one ; $4999\div 1109=4+563$ Step.2 :- Divide the smaller number by the above OPERATION's remainder; $1109\div563=1+546$ Step.3 :- Divide the remainder from the step 1 by the remainder of STEP2; $563\div546=1+17$ Step.4 :- Divide the remainder from the step 2 by the remainder of step.3; $546\div17=32+2$ Step.5:- Divide the remainder from the step 3 by the remainder of step.4; $17\div2=8+1$ Step.6 :- Divide the remainder from the step 4 by the remainder of step.5; $2\div1=2+0$ here we STOP , the remainder is zero and 1 is the last remainder thet is not zero. Hence, gcd of 4999 and 1109 is 1. Now, to represent in form of 4999m+1109n, we have $546=1109-1563\\546=1109-1(4999-11094)\\546=51109-4999\\17=563-546\\17=4999-41109-1109-563\\17=4999-41109-1109+4999-41109\\17=24999-91109\\2=546-1732\\2=-654999+2931109\\1=17-82\\1=5224999-23531109$ Hence, 1 = 4999(522)+1109(-2353) where, m=522 and n=-2353.

Find gcd of 4999 and 1109 and also express it in 4999m +1109n

Answer»

Given:-

Two prime numbers 4999 and 1109.

To Find:-

Find the gcd of 4999 and 1109 and also express it in 4999m+1109n.

Solution:-

According to question we have to find the gcd of 4999 and 1109.

Since, 4999 and 1109 both the numbers are prime numbers which can't be further break into other smaller prime numbers.

Therefore, here, we USE Euclid's Algorithm to find the gcd of 4999 and 1109:-

So, using Euclid's Algorithm , we have

Step.1 :- divide the larger number by the smaller one ;

$4999\div 1109=4+563$

Step.2 :- Divide the smaller number by the above OPERATION's remainder;

$1109\div563=1+546$

Step.3 :- Divide the remainder from the step 1 by the remainder of STEP2;

$563\div546=1+17$

Step.4 :- Divide the remainder from the step 2 by the remainder of step.3;

$546\div17=32+2$

Step.5:- Divide the remainder from the step 3 by the remainder of step.4;

$17\div2=8+1$

Step.6 :- Divide the remainder from the step 4 by the remainder of step.5;

$2\div1=2+0$

here we STOP , the remainder is zero and 1 is the last remainder thet is not zero.

Hence, gcd of 4999 and 1109 is 1.

Now, to represent in form of 4999m+1109n, we have

$546=1109-1*563\\546=1109-1(4999-1109*4)\\546=5*1109-4999\\17=563-546\\17=4999-4*1109-1109-563\\17=4999-4*1109-1109+4999-4*1109\\17=2*4999-9*1109\\2=546-17*32\\2=-65*4999+293*1109\\1=17-8*2\\1=522*4999-2353*1109$

Hence, 1 = 4999(522)+1109(-2353) where, m=522 and n=-2353.

45.

The cmpound interest on rs.4000 at the rate of 10% for 2 years is

Answer»

CI = PRINCIPAL (1 + rate/100)^t - Principal

= 4000 (1 + 10/100)^2 - 4000

= 4000 ( 1 + 1/10) ^2 - 4000

= 4000 ( 11/10) 2 - 4000

= 4000 * 11/10 * 11/10 - 4000
