Question
If a number is increased by 30% and 12 is subtracted
from it, the result is the same as 9.6 more than 30% less of the original number. What is the number which is 10 more than the original number?Solution
ATQ,
Let the original number be x According to the question, 1.30x – 12 = 0.70x + 9.6 Or, 0.60x = 21.6 x = 21.6 / 0.60 = 36 Therefore, required number = 36 + 10 = 46
