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.

 (54 (permalink)) aynaval    Institute: mdi, gURGAON Status: Offline Posts: 5 Join Date: Oct 2007 Re: CRACK THE CAT - DOUBT OVER MATHS (PROBLEM SOLVING) - October 15th, 2007 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.

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.
