Question:-
A baker needs sugar syrup that is 40% sugar. How many gallons of water should he add to 5 gallons of 70% sugar syrup to make the 40% sugar syrup?
Correct answer:-
300g × 40/100 = 120g.
So its 120g sugar and 180g water.
Now to make it 50%, we should add 60g sugar. That makes it 180g sugar in 180g water.
3.75 gallons should be added.

Answer:
Answer:Solution
Answer:SolutionGiven:
Radius (r) of cylindrical part = Radius (r) of hemispherical part = 22.8=1.4 cm
Length of each hemispherical part = Radius of hemispherical part =1.4 cm
Length (h) of cylindrical part =5−2 × length of hemispherical part
⇒5− 2×1.4=2.2 cm
Volume of one gulab jamun = Volume of cylindrical part + 2 × Volume of hemispherical partWe know that, volume of a cylinder is πr2h
and volume of a hemisphere is 32πr3
∴ Volume of one gulab jamun =πr 2h+2× 32
πr 3=πr 2 h+ 34 πr 3
⇒π×(1.4) ×2.2+ 34
π(1.4) 3
⇒ 722 ×1.4×1.4×2.2+ 34× 722
×1.4×1.4×1.4[∵ π= 22/7 ]
⇒13.552+11.498=25.05 cm
Hence, volume of one gulab jamun =25.05 cm
So, volume of 45 gulab jamuns =45×25.05=1,127.25 cm
Also, given that, volume of sugar syrup =30% of volume of gulab jamun
∴ Volume of the sugar syrup of 45 gulab jamuns = 10030×1,127.25
⇒338.17 cm
3 ≈338 cm
Hence, the amount of syrup in 45 gulab jamuns is approximately 338 cm
