Sir question 9 m doubt h ...(4:9)=12x kyun kia? Aur L:G =12x:16x kyun kia?

[@vishal40269]

Que.9 1yr ago salary of L:G 3:4 take it as 60:80. Now salary of lxman from last to this year given as 4:5 we can say it is increase of 25% (if you know reciprocal in percentage) same for gopal increase of 50%. Remember 60:80. Increase them 25%:50%. I.e 75:120. Lxman salary is 75/195 *4290 solve this and u get answer

+studysmart: Sir., please explain why the number 4 was multiplied in Q.No:9. Many students have raised the same question. Please please explain.

[@ytg6663]

For easy calculation.. sir Had solved question already but he saw that there a fraction us obtained when we do it in normal way without multiply by 4..

[@sakibdalvi7719]

Wahi to....i mean aap aise sirf particular question ko hi kr skte ho...smart approach aap har kisi question me kar dete to alag baat thi...exam me value thodi na same ayegi..... Smart approach se mt jao..sidhe concept ko smjh ke hi krna

[@Ivaandahiya]

He use 4 because 4 is least no when we multiply to both it give that value which do not give any effect to their ratio The no is depend on value so dont confuse

[@reenareads365]

[@ScoRPy22]

L:G= Ratio between Lax. and Gop. = 3:4 L:L'=Ratio individual salary of Lax. = 4:5 G:G'=Ratio individual salary of Gop.= 2:3 Now, L:G = 3x:4x [Meaning L=3x and G=4x] Put this in L:L' and G:G' we get 3x=4/5 and 4x=2/3 meaning we get value of each unit of salaries of Lax. and Gop. as 1= 15x/4 and 1=6x Since addition of their salaries is 4290. So, 15x/4 + 6x = 4290 By solving we get x=440 Now put this in the value we got of their 1 unit So Lax. = 15(440)/4= 1650 and Gop = 6(440)= 2640

By traditional methods, you can't clear any competitive exams.

[@DineshKumar-tj5hf]

@@PradeepSinghRajputOfficial bro 12x or 16x kese aya???

[@sourabhpatidar6619]

4/9 = 12x this means 1/9 = 3x (if we devide both sides by 4 or in simple terms cancel out)and here we need to calculate value of 5/9 in terms of x which will be 5 multiplied by 1/9 which will be same as 5*3x or = 15x. Hence the previous salary was 12x and new salary is 15x. I hope this helps a little bit.

ques 9) ratio of laxnan's last year and this year salary is 4x and 5x. ratio of gopal's last year and this year salary is 2y & 3y. given that , 4x/2y=3/4 which gives 8x=3y -----------(i) also 5x+3y=4290 -------------(ii) solving eq i and ii, we get x=330. so laxman's current salary is 5x=5*330=1650

Bcoz he wants to maximize the ratio's i.e. if u will multiply with 3 then ratio becomes 9:12 but if u multiply with 4 then ratio becomes 12:16, however the ratio should not be disturbed...and also more is the number less time is required to cancel at last step...Hope it helps....
