The sum of three numbers is 98. The ratio of the first to the second is 2/3, and the ratio of the second to the third is 5/8. The second number is: (a) 15, (b) 20, (c) 30, (d) 32, (e) 33 Share with your friends Share 0 Varun.Rawat answered this Let the 3 numbers be x, y and z.Now, xy = 23 ⇒x = 2y3Now, yz = 58 ⇒z = 8y5Now, x + y + z = 98⇒2y3 + y + 8y5 = 98⇒10y + 15y + 24y15 = 98⇒49y15 = 98⇒y = 30So, second number = 30 0 View Full Answer Adarsh Saini answered this Let the three numbers be x, y and z. Sum of the numbers is 98. x + y + z = 98………………(i) The ratio of the first to the second is 2/3. x/y = 2/3. x = 2/3 × y. x = 2y/3. The ratio of the second to the third is 5/8. y/z = 5/8. z/y = 8/5. z = 8/5 × y. z = 8y/5. Put the value of x = 2y/3 and z = 8y/5 in (i). 2y/3 + y + 8y/5 = 98 49y/15 = 98. 49y = 98 × 15. 49y = 1470. y = 1470/49. y = 30 . Therefore, the second number is 30.Answer: (c) 1 Mustafa Latifi answered this i dont know 1 Sadiya Maheen Siddiqui answered this y=30 c is the answer 1
