Thomas and Matt has some money with them in the ratio of 3:4. If their father gives Rs.30 to each of them then the ratio becomes 4:5. What would be the ratio if Thomas spend Rs.40 and Matt spend Rs. 20 from what they have now?
Options.
A) 1:2 B) 2:3 C) 3:4 D) 4:5 E) 5:6
Let money of Thomas and Matt be x and y respectively.   x/y = 3/4 =&gt; x = 3/4 y   (x+30)/(y+30) = 4/5   =&gt; 5x+150 = 4y+120 =&gt; 5x = 4y-30   But x = 3/4 y   5* 3/4 y = 4y-30   15y = 16y-120 =&gt; y = 120   =&gt; x = 3*120/4 =&gt; x=90   Ratio of their money, if Thomas spend Rs.40 and Matt spend Rs. 20 =&gt; (90-40)/(120-20) = 50/100. =&gt; 1:2   1:2nswer:1:2
