Mtlb present ages to Rajesh 24 or Uma 8 hogi
But uske baad bhi Rajesh 4 yrs hence =24+4=28 yrs

Q no. 12 solution
Ratio of saving of A:B:C=4:3:6
SAVING BY A =4X
SAVING BY B =3X
SAVING BY C=6X
Spending of A =75%
SAVING OF A =25% =4X (GIVEN)
INCOME OF A = 100% = 4* 4X=16X
SPENDING OF B = 80%
SAVING BY B = 20% = 3X(GIVEN)
INCOME OF B = 100%= 5*20% =5*3X=15X
SPENDING OF C = 60%
SAVING BY C = 40% = 6X (GIVEN)
INCOME OF C = 100% =( 5*40% )/2= (5*6X)/2 =30X/2 = 15X
NOW TOTAL INCOME = 32,200
INCOME OF A+INCOME OF B+INCOME OF C= 32,200
16X+15X+15X=32,200
46X=32,200
X=700
DIFFERNCE BETWEEN INCOME OF (B+C) AND A= (15X+15X) - 16X
=30X - 16X
=14X
=14*7OO (AS X=700)
=9800. Ans
Itna achha explain to sir b nhi krte 😍aap mujhe b padha do pls
Thank you:)
Thank u 😊
Tnx bhai 🙏
Thanx dear
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

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 :)
bravo

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.
Wo 75% aur 80% aur 60% kese aya

If Q. 12 ans. = 9800 , kindly anyone help me in this
Given, Total income A+B+C = 32,200
Exp. Ratio = 15 : 16: 12 ( 75% : 80% : 60: )
Saving Ratio = 4 : 3 : 6
then,
acc. to this our income ratio comes out to be
Inc. Ratio = 19 : 19 : 18
So, Total income acc. to this = 56
i.e. 56 = 32,200
1 = 575
(B+C)-A = 37 - 19 = 18
18 × 575 = ₹ 10, 350

Question number 10 explanation.... please 🙏🏻
At 42:05 can anyone explain how he converted 66(2/3)% to 2/3 so fast ?
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
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.

Q7 - 3:1
Q8 - 31:33:35
Q12 - 9800
12 solution please
Spends 75% of income A means 25% of income A =4(saving of A)
I(A) = 16
Spends 80% of income B means
20% of income B= 3(saving of B)
I(B) = 15
Similarly, spends 60% of income C means 40% of income C = 6(saving of C)
I(C) = 15
Total income = 32200(given)
16x +15x+15x = 32200
46x = 32200
x = 700
So, income of (B+C) - income of A= (15x+15x) - 16x = 14x = 14*700= 9800

Q.7 -3:1(e)
Q.8 -31,33,35(a)
Q.12-9800(a)
spends 75% of income A means 25% of income A =4(saving of A)
I(A) = 16
Spends 80% of income B means
20% of income B= 3(saving of B)
I(B) = 15
Similarly, spends 60% of income C means 40% of income C = 6(saving of C)
I(C) = 15
Total income = 32200(given)
16x +15x+15x = 32200
46x = 32200
x = 700
So, income of (B+C) - income of A= (15x+15x) - 16x = 14x = 14*700= 9800

Can u plz explain 7 and 12
@@priyamishra9243 Q12 A+B+C=32,200
Exp. Of A,B,C 75% 80% 60%
So Saving of A,B,C 20% 40%
And saving Ratio is given 4:3:6
(25%×4=100% means Income)
So Ratio of income is
4×4=16
3×5=15
6×2.5=15
16:15:15 is Income Ratio of ABC
Total is 46=32200
So 1=700
A:B+C
16:30 difference is 14
So 14×700=9800 ans✔️
