Question
If x runs are second by Rohit, y runs by Shreyas and z
runs by Virat, then x : y = y : z = 7:4. If total number of runs scored by Rohit, Shreyas and Virat is 744, the find the number of runs scored by Shreyas?Solution
⇒ x : y = 7:4 = 49 : 28 ⇒ y : z = 7 : 4 = 28 : 16 ⇒ x : y : z = 49 : 28 : 16 Since total runs scored by Rohit, Shreyas and Virat = 744 ⇒ 49a + 28a + 16a = 744 ⇒ 93a = 744 ⇒ a = 744/93 = 8 Hence, Runs scored by Shreyas = 28 × 8 = 224
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.)...
5999.93 ÷ 60.005 × 70.002 = ? × 24.9
?% of 309.99 = 40.01% of 249.99 + 295.98% of 49.99
16.11 × 9.96 – (238.19 – 64.04 × 2.18) = ?
20.06% of 359.89 - 15.95 X ? + 18.07 X 14.95 = 48.87 X 6.02
2550.03 ÷ 74.98 x 49.9 = ? + 20.32
56237.05 + 10616.99 - 137.25 + 1795.33 = ?
- 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.)
30.33% of 440.08 + 45.09 × 5.998 – √961.09 × 3.990 – 189.99 = ?
