Answer:
68 bicycles.
Step-by-step explanation:
Let there be x bicycles, then there are (93 - x) tricycles.
From the given values:
2x + 3(93 - x) = 211
2x + 279 - 3x = 211
-x = 211 - 279 = -68
x = -68/-1 = 68.
No. of gallons required = csa of cuboid+area of rectangle/300
= 2(l+b)h + l*b /300
= 2(11+12)8 +11 *12 /300
=368+132/300
= 500/300
=5/3 =1.666.... =1.7
= 2 approx.
therefore 2 gallons should be used
