Possible then solution please

Tq??

q1- 6:1

q2-20k

4-63

5-8165

6-144km

bro….q2 ans is 40k..:)

Dear can u take screenshot of solved que in one place 4 me… foolish in quant ..

yes sirr…..say u want ans of all questions or selected ones??????

Really…why not all…will need to see all…

yaaaa …….

(x+y)/(x-y) =7/5

=>12y =2x

=>x/y =6/1

2)

totl =100

equal parts =50 =(w) & 50 =(s)

money spnd by wife =20% of 50 =10 => remaining =40 (w)

money spnd by son =40% of 50 =20 => remaining =30 (s)

now 10 =4000

=>100 =40000

3)2(pi)r +2r =29

=>2r (29/7) =29

=>r =7/2

=>area =(pi) r^2 =22/7 *49/4 =38.5 cm^2

4) new avg =(65*4+55)/5 =63 cm

5) 100 =7100 =>115 =8165 =sp

6) t(m) =400/(45+80) =3.2hrs

=> distance travelled by a =45*3.2 =144km

7) a =2/5 b ,b =b and c =2a =4/5b

=> ratio= 2/5b *12 :b*10 :4/5b*8

=> r =24/5 :10 :32/5

=> r =24:50:32 =12:25:16

3rd ans is wrong na,bcos side of square is given,thn perimeter will be 4*29?

yaaaa typo

Okk

____/____

thanku,wt is the ans of 8,9?

wre is 8th & 9th one???

Find the age wala ques..

yha to sirf 7 questions hi shw ho rhe wait i refresh..:)

Ratio of milk and water is 4:5. 15 ltr taken out from mixture, then added 12 ltr to both, and ratio becomes 5:6. Find the previous quantity of milk and water.

Radhika’s age is 5/8 of Seema’s. After 4 years, sum of their ages will become 60 years. Find Radhika’s age 7 years ago.

milk 12L N water 15 L…..?

RADHIKA AGE 19 YEAR…..?

4:5=4/9 1:1=1/2

5:6=5/11

9==108 2==24

108+15=123

5x+4+8x+4=60

x=4

5*4-7=13 year

Ratio of milk and water is 4:5. 15 ltr taken out from mixture, then added 12 ltr to both, and ratio becomes 5:6. Find the previous quantity of milk and water.

didnt get this one pls help

appox 6 ltr aa rha h but kuch mistk h question mn i think..:)

m:w =4x:5x

now milk left => m(l) =4x-4/9*15 =4x-20/3

similarly water left =>w(l) =5x-5/9*15 =5x-25/3

now 12 liter is added to both

=> m(l) =(4x-20/3)+12 =(12x+16)/3

=> w(l) =(5x-25/3)+12 =(15x+11)/3

now a/c

(12x+16)/(15x+11) =5/6

=> x =41/3

=> initial quantity of milk =4/9*41/3 =164/27 =6.07 ~6 ltr

54.66::::68.33

Plz solve this one _/_

Radhika’s age is 5/8 of Seema’s. After 4 years, sum of their ages will become 60 years. Find Radhika’s age 7 years ago.

r =5/8s——–(1)

(r+4) +(s+4) =60

=> r+s =52——(2)

now put 1 in 2

=> r+8/5r =52

=>13/5r =52 =>r =20

now 7 years ago age =20-7 =13yrs

there ?
