(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

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

19. \$קгค๔єєק\$

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

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
