    Let the present ages of M and N be 5x years and 3x years respectively. Given (5x−4):(3x+4)=1:1 ⇒ 5x−4=3x+4 ⇒2x=8⇒x=4 ∴ Present ages of M and N respectively are (5×4) years and (3×4) years i.e., 20 years and 12 years ∴ Required ratio =12−420+4​=824​=13​=3:1

    12)12)ans y. Now expenses will be a2,b2,c2 and the savings will be A,B,C. So a2 = 75% of a1 So b2 = 80% of b1 So c2 = 60% of c1 Now A = a1 - a2 = a1 - 75/100 x a1 = 1/4 a1 Now B = b1 - b2 = b1 - 80/100 x b1 = 1/5 b1 Now C = c1 - c2 = c1 - 60/100 x c1 = 2/5 c1 Given a1 + b1 + c1 = 32,200 --------------1 Ratio is 4:3:6 So we have 1/4a1: 1/5b1 : 2/5 c1 = 4:3:6 So ¼ a1 = 4 Or a1 = 16 p So 1/5 b1 = 3 Or b1 = 15 p Also 2/5 c1 = 6 Or c1 = 15 p Now substituting the values in 1 we get 16 p + 15 p + 15 p = 32,200 46 p = 32,200 Or p = 700 So salary of A = 16 x 700 = 11,200 Salary of B = 15 x 700 = 10,500 Salary of C = 15 x 700 = 10,500 According to the question income of A = 11,200 Income of B + C = 21000 Therefore difference of A and B + C will be 9800y.

    we can write 66(2/3) as 66 + (2/3) so it will be 66+.67 = 66.67 and we know that 66.67% is 2/3 , hope u will understand

  • @Payanura

    2 жыл бұрын

    66(2/3)% means your converting mixed fraction to proper fraction. So, first multiply 3*66 = 198. Then add 2 to it you'll get it as 200/3 %. Now percent is 1/100 , so in short our calculation becomes 200/3*100 = 2/3. So. 66(2/3)% = 2/3.

    Q12 RATIO OF Savings to Spending OF A B C is 1:3, 1:4, 2:3 ------------------(1) Savings ratio is given as 4:3:6 Then make all the above saving to spending ratio as the above numbers (To get the exact unit value of per total value ) SO the new values of (1) are 4:12 , 3:12 6:9 ( see the 4,3,6 in the ratio proportions I have made ) Hence the total salary of A,B,C are 16,15 and 15. SUM = 46 Hence 46 units are Rs.32200 so 1 unit = Rs.700 We are required to find Difference between salaries of A (which is 16) and B+C ( which is 15+15=30) DIFFERENCE = 14 14 units = 14*700 = Rs.9800 Sorry if my explanation is not legible but this is the only way I can explain a question by shortcut method digitally. Let me know if you guys understood this. Thanks :)
