|
Answer»
Let Reena's present age be = 'x' YEARS. Therefore, Sonu's present age will be = '2x' years Reena's age 3 years ago = 'x-3' years Sonu's age 3 years ago = '2x-3' years A/Q, 2x-3 = 5(x-3) 2x-3 = 5x-15 2x-5x = 3-15 [on transposition] -3x = -12 x = -12/-3 Hence, x = 4 Hence,
Reena's present age = 4 years Sonu's present age = 2x years = 2*4 years =8 years This took me a lot of effort Hope it helped you Please mark me as brainliest Please.. |

|
Answer» Step-by-step EXPLANATION: Given Question:-From the given data, Find the missing frequencies x and y. Solution:-The mode of the given data = 33 Modal class = 30-40 Total number of frequencies = 100 =>56+x+y = 100 =>x+y = 100-56 =>x+ y= 44------(1) so we have frequency of the modal class (F 1) = 28 frequency of the preceding the modal class =(f 0) = X frequency of the succeeding the modal class = (f 2) = Y Lower limit of the modal class (l) = 30 Size of the class (h)=10 We KNOW that Mode = l +[(f1-f0)/(2f1 -f0-f2)]×h On Substituting all the values in the formula then =>33=30+[(28-X)/(2(28)-X-Y)]×10 =>33-30 = (28-X)/(56-X-Y)]×10 =>3=(28-X)/(56-(X+Y)]×10 =>3 = [(28-X)/(56-44)]×10 (from (1)) =>3 = [(28-X)/12]×10 =>3=[(28-X)×10]/12 =>3×12 = (28-X)10 =>36=(28-X)10 =>36/10 = 28-X =>3.6 = 28-X =>28- X = 3.6 =>X = 28-3.6 =>X = 24.4 From (1) X+Y = 44 =>24.4+Y=44 =>Y=44-24.4 =>Y= 19.6 The VALUE of X = 24.4 The value of Y = 19.6 Answer:-The values of Missing numbers in the given data are : The value of X = 24.4 The value of Y = 19.6 Used formula:-
