In 2005, there were 1050 students at a school. If the number of students at the school increased by 50 percent from 1995 to 2000, by what percent did the number of students at the school increase from 2000 to 2005?
(1) The number of students increased by 110 percent from 1995 to 2005 at the school.
(2) There were 500 students in 1995 at the school.
The answer is option D
State 1 : lets take no. of students initially in 1995 as x
so, x+110%of x =1050
we can calculate the initial no. students in 1995 i.e., 500
there was 50% increase from 1995 to 2000
so we can calculate the % increase in no. of students from 2000 to 2005...sufficient
State 2:500 students were there in 1995
same as state 1 we can calculate the 50% increase
and we are given that 1050students were there in 2005
we can subtract and calculate the % increase ... sufficient
