• 30.5 written as 31...67.2 wrttn as 67...so 183.9 will be 184
• 10 years agoHelpfull: Yes(6) No(1)
• 3)(49+6)-25=30,
  (4+36)-5=35,
  (81+5)-x=40
  x=46

• 1)"184"
  sol : 30.5 round of 31
  31 round of 30
  30 round of 0
  lly, 67.2 round of 67
  67 round of 70
  70 round of 100
  lly, 183.9 round of 184 then 190,200

• 8)(-3,-6,-9), (-82,-80),(-30,-33,-36),(-55,-53),(-24,x,y)
  -3 2 -3 2 -3
  
  in first term -3 is difference and in 2nd term 2 is the difference
  
  so -24-3=-27
  -27-3=-30

• 8) (-3,-6,-9),-82,-80 (-30,-33,36),-55,-53,(24,x,y)
  in the brackets the differnce is -3 and reaming the differnce is 2
  we require the answer in brackets so 24-3=21

• 3.(49+6)-30=25
  (4+36)-35=5
  (81+5)-40=46
  
  ans 46

• 2)99 is ans break into 3 series 62= 52+10,or 42+20
  89=78+11,or 68+21,
  61=49+12, or 39+22
  76=63+13,or 76+23

• 3) 49, 25,36,81 these are are the squares of 7,5,6,9 respectively
  7-5=2
  5+1=6
  6+3=9
  9+5=14
  so ans will be 196... but m not sure..

• 3) ans-169
  49,6,25,4,36,5,81,5,?
  7,5,6,9,?
  7-2=5
  5+1=6
  6+3=9
  9+x=?
  
  -2,1,3,x
  -2+3=1,
  1+2=3,
  3+1=4
  so x=4
  
  9+4=13
  13^2=169

• 5) 2/3,5/3,32/6,72/3,_
  Ans) (2/3)+1=5/3
  (5/3)+1=8/3-->(8/3)*(4/2)(i.e 2)=32/6
  (32/6)+1=38/6-->(38/6)*4=72/3
  (72/3)+1=75/3-->(75/3)*6(i.e 12/2)=900/6(or)150
