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.

Although I corrected my mistake I did this one for free fore next question you need to pay !
