Question

What least number must to be added to 1056 to get answer exactly divisible by 23

Answer 1

Answer:

Step-by-step explanation:

Dude, 80 g must be evaporated...

now, we see that 24% is alcohol.....

=>   $\frac{24}{100}$ x 400 = 96g of alcohol is present

in order to increase the concentration from 24% to 30%, let the amount of other chemicals to be vaporized be 'p'

now, $\frac{30}{100}$ = 96g (96 still remains, since other products must be evaporated in order to increase the concentration)

=> 400-p = 320

=> 400-p = 320

=> p = 400-320

=> p = 80g
