= 20/100 * 1/4 * 10,00,000 = Rs. 50,000.
Charges for managing business =
Rs. 1000 * 12 = Rs. 12,000.
Assume, yearly profit be 'x', then
Ram's share : Shyam's share = 5 :2
i.e.
Ram's share = 5/7 x and Shyam's share 2/7 x.
Now, Ram's income = 4 (Shyam's income)
5x/7 - 12,000 + 50,000 = 4(2x/7 - 50,000 + 12,000)
5x/7 + 38,000 = 8x/7 - 1,52,000
3x/7 = 1,90,000
x = 13,30,000/3 = Rs. 4,43,333.
i.e. Rs. 4,40,000.
Hence, 3]
| That's the same thing i've done and i got the same answer.... but was confused about which choice would be correct., since it is not given amongst the choices.

Hi,
Just take any two numbers greater than 0...since we are talking abt variables, the rule shud be the same for any number thats greater than 0.
Say 5 and 7. a=5 and b=7.
now |5-7|=2 and |7-5| is also 2. Therefore, option 3.
For any two positive numbers, this will be true. Once the absolute sign is there, then a-b and b-a will be equal.
Regards

Answer is 3. a<0 | Simple thing is that from the given conditions, a should be always less than 0. So, if b is 3 or -3 and a = -5
So b can be positive or negative but a will always be negative.
