Question

the cost of 8kg of sugar is rs.360 what will be the cost of 15kg of sugar​

Answer 1

Step-by-step explanation:

if 8 kg of sugar will be 360

then 1 kg of sugar = 360÷8 = 45

then 15 kg of sugar = 45*15

= rs.675

Answer 2

Answer:

$\red\bigstar$ The cost of 15kg of sugar​ = ₹675.

SOLUTION

Cost of 8 kg of sugar = ₹360

Therefore,

$\sf Cost\: of \; 1\: kg \: of \: sugar = \dfrac{Cost \; of \: 8\: kg \;of \;sugar }{8}$

$\implies \sf Cost\: of \; 1\: kg \: of \: sugar = \dfrac{360 }{8}$

$\implies$ Cost of 1 kg of sugar = ₹45

Now,

Cost of 15 kg of sugar = Cost of 1 kg of sugar × 15

$\implies$ Cost of 15 kg of sugar = 45 × 15

$\implies$ Cost of 15 kg of sugar = ₹675.
