If two numbers are in the ratio 5:2. If 10 is added to both of the numbers then the ratio becomes 5:4 then find the largest number?  Pick:
A) 3	B) 7	C) 4	D) 5	E) 6
5:2   5x + 10 : 2x + 10 = 5 : 4   5[2x + 10] = 4[5x + 10]   10x + 50 = 20x + 40   20x - 10x = 50 - 40   x = 1   Then the first number is = 5X   5x = 5   Option '5'
