Question
The ratio of the monthly income of Gaurav and Himesh is
11:16, respectively, and their expenditures are Rs. 2000 and Rs. 4000, respectively. Find the difference between their incomes if the ratio of the monthly saving of Gaurav to Himesh is 7:10.Solution
According to the question: Let the monthly income of Gaurav = Rs. 11w Monthly income of Himesh = Rs. 16w According to the question, (11w – 2000):(16w – 4000) = 7:10 10(11w – 2000) = 7(16w – 4000) 110w – 20000 = 112w – 28000 28000 – 20000 = 112w – 110w 8000 = 2w w = 4000 Difference between their incomes = 16w – 11w = 5w = 5 × 4000 = Rs.20,000

48 ÷ 4 × (3 + 5) – 6² + 10 = ?
What will come in the place of question mark (?) in the given expression?
9 (? + 12) = 3 (14 + 17 - 11)
(2500 ÷ √625) × √(42.25) = ? ÷ 4
(15/8) x [6924 – 2124] + 910 = ? + 190
What will come in the place of question mark (?) in the given expression?
412 + 25% of 2400 = ? + 1131
37% of 810 – 32% of 460.5 = ?
√3970 × √730- √2400 =?
Simplify the following expression:
1280 ÷ 8 + 490 ÷ √49 + ? = 150 * 2
