anyone can tell me the short cut trick to solve que. no 49…?
((14+28)%of 8000)-((13+18)%of 3500) or
what about question 48
wat abt 48
For qus 48:
10% of 3500:25% of 3500
10:25 direct =2:5
PLS SOLVE IT AND EXPLAIN IT, DON’T USE LONG METHOD AND FORMULA
Ans – A
When answers are such complicated, best method is going through the “OPTION METHOD”. Scan through the options and select one which you find more suitable answer, pick that and do the below method:
(590.74 x 20% ) + 590.74 = 708.89 (Cost of Horse)
(540.74 x 50% ) + 540.74 = 811.11 (Cost of Mule)
So option 1 is your answer.
There is direct method but it takes time to calculate, but for the one who do maths speed its ok!
120X + 150Y = 152000 (or) 12X + 15Y =15200 (or) 5X + 4Y = 5116.6 —- 1
150X + 120Y = 153500 (or) 15X + 12Y =15350 (or) 4X + 5Y = 5066.6 —- 2
by equating the two equations you will get both X and Y.
better take the last two equations for simpler calculations.
