Question
Out of his monthly income of Rs. 30,000, Arjun spent (R
- 5)% on rent, (R + 10)% on others and saved Rs. 6,000. Find R% of his monthly income.Solution
ATQ, Savings of Arjun = 30,000 - (R - 5)% of 30,000 - (R + 10)% of 30,000 = 30,000 - 300R + 1,500 - 300R - 3,000 = Rs. (28,500 - 600R) So, 28,500 - 600R = 6,000 Or, 600R = 22,500 Or, 'R' = 37.5 Required value = 0.375 × 30,000 = 11,250
?% of 320 = 40% of 40 × 5
(22² × 8²) ÷ (92.4 ÷ 4.2) =? × 32
42% of 400 + 38% of 800 + ?2 = 728
What will come in place of (?) in the given expression.
{(60% of 250) + √144} ÷ (3² - 4) = ?- What will come in place of (?) in the given expression.
√324 + √121 – √49 = ? Determine the simplified value of following expression:
0.998 + 0.882 + 0.12Â
√225 + 27 × 10 + ? = 320
(26)2 = {(20% of 40% of 18200) ÷ ?} × 1664 ÷ 128Â
(2 ÷ 3) × (4 ÷ 12) × (? ÷ 10) × 45 × (1 ÷ 5) = (? ÷ 6) + (2 ÷ 5)
What is the value of 143 + 163 + 183 + … + 303?
