40 : 30 = x : 63 ⇒ x = (40*63)/30 = 84
y = 59°
35kg - a mass of sugar syrup
30% of 35kg it's a mass of sugar
30% = 30 : 100 = 0.3
30% of 35kg = 0.3 · 35kg = 10.5kg - a mass of sugar
Add xkg water. Then we have (35 + x)kg of sugar syrup and still 10.5kg of sugar.
10.5kg is 25% of (35 + x)kg .
(35 + x) -- 100%
10.5 -- 25% <em>multiply both sides by 4</em>
42 -- 100%
Therefore we have the equation:
35 + x = 42 <em>subtract 35 from both sides</em>
x = 7
<h3>Answer: We should add 7kg of water.</h3>
