Answer:
Cost of ten bananas and ten pears is £
3.90
Step-by-step explanation:
As three bananas and two pears cost 95
p and five bananas and three pears cost £ 1.51 or 151 p
,
subtracting former from latter, we get
two bananas and one pear cost 151
p − 95
p = 56
p
and doubling four bananas and two pear cost 56
p
×
2
=
112
p
Hence, one banana costs 112
p − 95
p = 17
p
.
and two bananas cost 17
p × 2 = 34
p
and hence one pear costs 56
p − 34
p = 22
p
Hence cost of ten bananas and ten pears is
10 × 17
p + 10 × 22
p = 170
p + 220
p = 390
p = £
3.90
