Question
A man earns 7/4 times in March, May, July, and December
than his average earning of ₹ 8000 per month in the rest of the months. So his savings in the March, May, July, and December goes to 3/2 times than that of the rest month’s savings of ₹ 6000 per month in the year. What is his average expenditure per month?Solution
Earning in the remaining 8 months = 8000 × 8 = ₹ 64000 Earning in March, May, July, December (4 months) = (8000 × 7/4) × 4 = ₹ 56000 ⇒ Total earnings (12 months) = 64000 + 56000 = ₹ 120000 Savings in the remaining 8 months = 6000 × 8 = ₹ 48000 Savings in March, May, July, and December (4 months) = (6000 × 3/2) × 4 = ₹ 36000 ⇒ Total savings (12 months) = 48000 + 36000 = ₹ 84000 ∴ Total expenditure (12 months) = 120000 - 84000 = ₹ 36000 ⇒ Average expenditure per month = 36000/12 = ₹ 3000
What should come in place of the question mark (?) in the following question?
2 – [6 – {3 + (–4 + 5 + 1) × 8} + 12] = ?
125% 0f 74÷37×48×? =192 ×√225
1555.5 + 1000.8 – 1354.3 = ? + 52
[(4 √ (7) + √ (7)) × (7 √ (7) + 6 √ (7))] - 87 = ?
...58% of 3300 - ?% of 2900 = 1740
15 * 12 + 35% of 80 + 70% of 130 = ?
What value should come in place of the question mark (?) in the following question?
