Total Students = 240
Pupils who likes Mango = 60
Pupils who likes Orange = 84
Pupils who likes Pineapple = ?
solve for Pupils who likes Pineapple,
Pupils who likes Pineapple = 240 - (60 + 84)
Pupils who likes Pineapple = 240 - (144)
Pupils who likes Pineapple = 96
so now solve for R of Pupils who likes Pineapple, using PBR formula,
P = B × R
where,
P = 96
B = 240
R = ? × 100%
solve for R,
P = B * R
96 = 240 * R
R = 96/240
R = 0.4 x 100%
R = 40%
Therefore the answer is letter D) 40%.
