Question

if we divide 50 into two parts such that ratio of 1/5 of the first part and 1/6 of the second part is 4:5.Then find the two parts.​

Answer 1

Answer:

20,30

Step-by-step explanation:

You can directly knock out with options if its an mcq or

.

1/5th of 20 is 4 and 1/6th of 30 is 5

The ratio comes 4:5.

Hence the answer is 20 and 30

Answer 2

Step-by-step explanation:

Let the two parts be X and 50-X then"according to the Question...

$\frac{1}{x} + \frac{1}{5 - x} = \frac{1}{12}$

=

$=> \frac{50}{x(50 - x)} = \frac{1 }{12}$

$=>x(50 - x) = 600$

$=> {x}^{2} - 50x + 600 = 0$

$=>(x - 20)(x - 30) = 0$
