Let solution A = A litres, 13% alcohol, used 4 times
Let solution B = B litres, 10% alcohol,
Clearly since solution A is 4 times to that of B solution hence, solution A will be 4B litres
13% of 4B + 10% of B = 124
52/100 B + 1/10 B = 124
53 / 100 B = 124
B = 12400/53
B = 234 mili litres
She used 234 mili litres of Alcohol B.
it's not right
Wait lemme cross check.
52/100 B + 10/100 B = 124
62 / 100 B = 124
B = 12400/62
B = 200 mili litres
She used 200 mili litres of Alcohol B.
I am sorry I did a silly calculation mistake, this is the right answer,
ok since that you did a a mistake can you just answer this one cause they gave to me because of your mistake
so can you answer itt please ?
Salma invested her savings in two investment funds. The amount she invested in Fund A was
7%( X - 8000 ) + 2% ( X ) = 790
7/100X - 560 + 2/100 = 790
9/100 X = 790 + 560
9/100 X = 1350
X = 15000................................................Sum invested in B.
