Question
The ratio of A's income to savings is 25:9, and B's
expenditure is 60% of A's total income. If B's expenditure exceeds its savings by Rs. 3500, and A's income is 25% higher than B's income, find A's savings.Solution
Let the total income of A = 25x Then saving = 9x And expenditure = 16x Expenditure of B = 60% of 25x = 15x Then savings of B = 15x-3500 Total income of B = 15x+15x-3500 = 30x - 3500 Again, income of A = 125% of income of B Income of B = 25x/125 ×100 = 20x In bot the conditions income of B will remains the same 30x – 3500 = 20x X = 350 Savings of A = 9x = 3150
What will come in the place of question mark (?) in the given expression?
(55 × 8 + 28) × 10 = ?
[∛(91125/19683 )- ∛(3375/5832 ) ] × ∛(512/9261) = ? - √(484/3969)
- Determine the simplified value of the given expression.
(-6) × {21 – (–3) × (–6)} 961 × 4 ÷ 31 – 15% of 180 = ? – 73
(160 × 12 - 13 × 20)/(120 × 2 + 2 × 35 + 2 × 11) = ?
18 + 28 ÷ 4 - 14 = ? - 35
