Question
A sum of Rs. 642 is divided among X, Y and Z such that X
gets Rs. 144 more than Y. Y gets Rs. 90 more than Z. Find the share of Z?ÂSolution
Rs 642 is divided among X, Y and Z. Y gets Rs.(Z + 90) X gets Rs. (Z + 90 + 144) = Rs. (Z + 234) According to the question, => Z + 234 + Z + 90 + Z = 642 => 3Z + 324 = 642 => Z = 318/3 => Z = 106 Share of Z = Rs 106
26.11% of ? – 521.02 = 648.51
(23.99)2 – (17.99)2 + (1378.98 + 44.99) ÷ ? = 608
?% of 549.83 – 18.05 × 31.96 = 44.94% of 479.84 – 13.98 × 33.13Â
29.88% of 3599.90 + 5/12 of 2399.81 – 34.81% of 1200.18 = ?
(31.9)3 + (34.021)² - (16.11)3 - (42.98)² = ?
19.22 × 11.99 + 142.15 = ?
15.15% of (150.50 + 249.50) + 8.08³ - (10.10 of 5.05) = ? of (75.75 - 25.25)
Determine the simplified value of the given mathematical expression.
What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.) 1219.98 ÷ 30.48 × 15.12 = ? × 2.16
