Question
The average expenditure of a man for the first 6 month
is Rs.6000 and for the next 6 months is Rs.9000. If he saves 15000 in that year then find his average monthly income.Solution
Total expenditure in first 6 months = 6000 × 6 = Rs.36000 Total expenditure in last 6 month = 9000 × 6 = Rs.54000 Total income of the man in a year = 36000 + 54000 + 15000 = Rs.105000 So average income in a month = 105000/12 = Rs. 8750
What will come in the place of question mark (?) in the given expression?
√(? - 212) - 84 = 81 - 13 X 9
Evaluate: 18 ÷ 3 × 4 + 6 − 5
7(1/2) – 3(5/6) = ? − 2(7/12)
`2(1/3)` + `4(1/4)` + `4(2/3)` + `8(7/6)` + ? = `4(3/5)xx4(1/2)`
...89 ÷ 512 × (1/64) = (23)?
What should come in place of the question mark (?) in the following question?
2 – [6 – {3 + (–4 + 5 + 1) × 8} + 12] = ?
The value of 15 × 14 – 30 + (32 + 17) is:
1440 ÷ 12 + 540 ÷ √36 + ? = 180 * 3
[(15)³ × (8)²] ÷ (90 × 6) = ?²
What will come in place of the question mark (?) in the following question?
24.30% of 372.32 = ?
