2^x-2^(x-2)=3(2^13)
=>2^x(1-1/4)=3(2^13)
=>2^x(3/4)=3(2^13)
=>2^x=2^2 *2^13
=>2^x=2^(13+2)
=>2^x=2^15
=>x=15

after 10 pound gain there total weight is 350
if his brother is "x" kg then leo is 1.5*x
1.5x + x = 350
2.5 x = 350
x = 140
So current weight of LEO = 340 - 140 = 200 (340 - 140 since weight of his brother remains the same)
SO correct ans "E"
