W11 UTUU HUVILY.1. If ratio of two numbers is 31:23 and their sum is 216.Find these numbers.

Answer»

Let the common multiple be X(31X/23X)31X+23X=21654X=216X=431X = 31(4)=12423X=23(4)=92

thanks

let the first number be = 31x and the second number be= 23x

their sum=216

so,31x+23x=21654x=216x=216/54x=4

hence,the first number= 31x = 31*4=124the second number=23x=23*4=92

A pudding is made of 200 g sugar, 800 g eggs, 600g flour and 200 g dry fruits. What percent of sugaris present in the pudding?

Answer»

Solution :- Sugar=200=200gmSugar+Eggs+Flour+DryFruit=200+800+600+200 =1800=1800gm

Sugar Percentage=(200/1800)×100=0.1111×100=11.11%

solution :200=200gm / sugar+eggs+flour+dryfruit=200+800+600+200=1800gm sugar percentage = (200/1800)×100= 0.1111×100 = 11.11

3)find the H.C.E of 555 210.

Answer»

Firstly we will find the hcf of 55 and 210 by applying Euclid's division algorithm 210>55*210=55x3+45........(1)*55=45x1+10.......(2)*45=10x4+5..........(3)*10=5x2+0..........(4)so, HCF is 5from equation 3 we have 5=45-(10x4)

5 = 45 – (55 – 45)*4. ( from equation 2)

5 = 45 – 55*4 + 45*4

5 = 45 *5 – 55*4

5 = (210 – 55*3) *5 – 55*4

5 = 210*5 – 55*15 – 55*4

5 = 210*5 – 55*19

5 = 210a + 55b where a = 5, b = –19

Write a Pythagorean triplet whose one member is.(ii) 14(ii) 16

Answer»

I)6Let 2m = 6m = 3

m²+ 1 = 3²+ 1= 9 + 1 = 10

m²- 1 = 32- 1 = 9 - 1 = 8

check:

6²+ 8²= 36 + 64 = 100 = 10²

Hence, the triplet is 6, 8 & 10

ii) 14

Let 2 m = 14

m = 7

m²+ 1 = 7²+ 1 = 49 + 1 = 50

m²- 1 = 7²- 1 = 49 - 1 = 48

check:

14²+ 48²= 196 + 1304 = 2500= 50²

Hence, the triplet is 14, 48, and 50

iii) 16

Let 2 m = 16,

m = 8

m²+ 1 = 8²+ 1 = 64 + 1 = 65

m²- 1 = 82- 1 = 64 - 1 = 63

check:

16²+ 63²= 256 + 3969 = 4225 =65²Hence, the triplet is 16, 63 & 65Like if you find it in

10. Find a Pythagorean triplet whose one memberis 323.

Answer»

When n is a member of a pythagorean tripplet then the triplet is :

n² - 1

2n

n² + 1

In our case n = 323

Doing the substitution we have :

n² - 1 = 323² - 1 = 104328

2n = 323 × 2 = 646

n² + 1 = 104330

The tripplet is thus :

104328, 646, 104330
