Time taken by A + B is m days
Time taken by A is ‘m + a’ days
Time taken by A is ‘m + b’ days

Hey @Binocular @BlackMagic123 @The_integrous_one @RedStorm47 @anon87955785 @Plutus
I just failed in my bank exam. I scored only 52/100. 
. Cut off was 87.50 /100.
The exam was not very tough but my hand is not fast enough to solve 35 math questions in 20 minutes only.

Did you fail life?
Is this the end of the world?
Snap out of it! What’s past is past, you can’t change anything now.
Learn from your previous failures and leave the past behind you.
Let’s be honest, if you don’t fail, you’re not even trying. If you’re not trying, then you’re not living.
Now this isn’t your only exam in your whole intire life, there will always be hard and beautiful times in life.
There is nothing totally wrong in this world, even a stopped clock gives you the correct time twice a day.

I feel you.
And, it’s okay. You have to be patient in life and God is teaching this skill to you through these failures. Just don’t give in, The end of the beginning is the beginning of the end! You’re still in the middle, you have got a long way to go!
By the way, what do you plan doing now?

Damn.
No worries bro, keep practicing, keep working, solve as many problems as you can and you’ll become fast enough.
If some people are scoring that high, so can you, it’ll just take time and practice.

Given x² -9x +1 = 0 ,
x² +1 = 9x
Squaring both equations
x⁴ +2x² + 1 = 81x²
Hence
x⁴ -79x² + 1 = 0

A farmer had land that he wanted to divide between his three sons, so the division was as follows:
_The first son took 4/3 of what the second one took
_The third one took 2/5 of what the first one took plus 5 hectares
_The third one took more than the second one with 2 hectares
Determine the share of each one of the sons in hectares.
I personally created this for you guys, I hope you’ll like it.

f = 4/3 s => s = 3/4f
t = 2/5 f + 5 …(1)
t = s + 2 = 3/4f + 2 …(2)
¾f + 2 = 2/5f + 5
¾f - 2/5f = 3
7/20 f = 3
f = 60/7 hectares
s = 45/7 hectares
t = 59/7 hectares
I dont know if I am correct.
@Binocular , plz check and correct my mistakes
