33 is subtracted from one third of a number, then the obtained number is increased by 250 % .
5/7 of the number obtained is multiplied by 3/2 then its half is increased to 120 % .
when 225 is decreased from the obtained number, zero is obtained, then the number is

OPtion

1) 237
2) 6543
3) 399
4) 453
5) 465
6) 96
7) 600
8) 300
9) 666
10) 222

Solution

[{(?/3)-33}*3.5*(5/7)*(3/2)*(1/2)*1.2]-225=0 => ?=399
Note that number is increased by 250 % means the number will become 100% +250% = 350% of the
original number for this we should multiply the number to 3.5. Similarly number is
increased to 120 % means the number will become 120% of the original number for this
we should multiply the number to 1.2
