Answer:
He sold 12 chocolates for 1 Re.
Step-by-step explanation:
He bought 15 chocolates for 1 Rupee
He sold for a profit of 25%
Sale price = profit + cost price
SP= 25%of 1 + 1 Re

x= 15*1/1.25
x= 12
He sold 12 chocolates for 1 Re.
<span>For the answer to the question above,
4 shovels of sand are used for every 5 shovels of gravel
4s : 5g
How many shovels of gravel are needed for 64 shovels of sand?
64s : Xg
We need to calculate the value of X
4s : 5g
</span><span>64s : Xg
4s.Xg = 5g.64s
X = (5g*64s)/4sg
= 5*64/4
= 5*16
= 80
80 shovels of gravel are needed.</span>
