# Over a period of 6 months, a colony of rabbits increases in number by 25% and then by a further 30%. If there were originally 200 rabbits in the colony, how many were there at the end?

we must multiply 55% and (The original number)200

%(per cent) means per hundred.

so it is 55/100

then, 55/100 x 200 =110 rabbits

The rabbit increases by 25 % = 200 +200*25/100

= 200 +200/4

= 200 +50

= 250

further increases by 30 % = 250 + 250*30/100

= 250 + 25 * 3

= 250 + 75

= 325 rabbits are there at the end.
