Question
Income of A is 65% of the Income of B and A together.
The saving of B is 20% of his Income and equals to Rs. 1400. Find the difference between the incomes of A and B.Solution
Let the total income of A and B = Rs. x Income of A = x × 65% = Rs. 0.65x Income of B = x – 0.65x = Rs. 0.35x Savings of B = 0.35x × 20% = Rs. 0.07x According to the question, 0.07x = 1400 Or, x = 20000 Difference between their incomes = 0.65x – 0.35x = 0.3x = Rs. 6000
- What will come in place of (?) in the given expression.
(18.5 × 2) + (3.5 × 4) = ? If x + y + 3 = 0, then find the value of x3 + y3 – 9xy + 9.
40% of 50 + 50% of ? = 25% of 300 - 10% of 250
√10000 x √8100 - (50)² = √(?) + (80)²
1428 ÷ 17 = ? % of 120
- Identify x such that x% of 540 plus {1080 ÷ x of 9} × 6 gives 162
Simplify the following expression:
Simplify the expression:
(9x² - 25) / (3x + 5)
135 ÷ 3 of 5 = ? - 112
