If the sum of money doubles itself in 10 years, then the number of years it would triple itself is 15 years. It is based on a simple logic.

You can consider the sum as 1000. After 10 years it would be 2000.

After 15 years, the sum would be 3000 thousand. Hence, the answer to this question is 15 years.

let money be rs. 100r=10% t=?p=100 rs. i=rs. 100i=(p×r×t)/100100=(100×10×t)/100t=100/10t=10 years. ans.

the answer will be 324

please give me like Sir

Factor of 36 are 2,3,4,6,9,12,18,36

2,3,4,6,9,12,18,36 are the factors of 36

x^1/6 is the correct answer

Relative speed of train

400/36×18/5 =40 km/h

Relative Speed of train = Speed of train + Speed of man

=> 40 = Speed of train + 20

Therefore, Speed of train = 40 - 20 = 20 km/h

Ans :-

you will have to find the number of man-days and boy-days required to do the job and equate it.

5(12M+ 16B) = 4(13M + 24B) since the same work is done they will be equal

60M + 80B = 52M + 96B

8M = 16B or M = 2B substitute 2B = M and you will get the total man-days required to do the job and it is

5( 12M + 8M) = 100 man-days

so,

x(7M+10B) = 100M

x(7M+5M)=100M

solving this x =25/3 days so 7 men and 10 boys will have to work for 25/3 days to complete the job.

full answer

One way to look at it is as an indirect ratio (if I recall the term correctly, it's been over 50 years) .

20 men times 9 days equals 12 men times X.

So, if 20×9=180 then 12×X=180

Dividing 180 by 12 = 15

It would take 15 days

20 men =9 days1 man can take 220×9=180 daysso 12 man can take 180/12=15 daysto build the same wall.

thank you

Maya has coins=327Ann has coins=327-138=189 coins

by using the division algorithem

p(x)=g(x)*q(x)+r(x)

2x³+4x²+5x+7=g(x) x 2x +7-5x

2x³+4x²+5x+7-7+5x=g(x) x 2x

2x³+4x²+10x / 2x=g(x)

so we should divide 2x³+4x²+10x by 2x

by long division

so g(x)=x²+2x+5

The required number would be HCF of (400 - 9), (435 - 10) and (541 - 14).HCF of (391, 425, 527) = 17

391 =17*23

425 = 5 * 5*17

527 =17*31

Required HCF = 17.

many many thanks you

thanku very much

= Let the two numbers be x and y.

Given,= (x+y) / 2 = 7= x + y = 14 .... 1

= x*y= 45

= x = 45 / y ---- 2

Substitute two in one.= 45 / y + y = 14

=45 + y^2 = 14 y

= y^2 - 14 y + 45 = 0

= y^2 - 9 y - 5 y + 45 = 0

= y ( y - 9 ) - 5 (y - 9) = 0

= ( y - 9) ( y - 5) = 0

= y = 9, 5.

= x*y = 45For y = 9, x = 5For y = 5, x = 9.

Let the third term be x.

Therefore, the proportion is →

6:18::x:25

So, as we know product of means = product of extremes

= > 18x = 6×25

or, x = 6×25/18

or, x = 25/3

Answer → The third term is 25/3.

20 men eat 200 kg rice in 20 days1 man in 1 day can eat rice=200/(20×20)=0.5kgthen 30 man in 15 days will eat rice =0.5×30×15=225kg
