• On a scale of a map 0.75 cm represents 6.48 km. If the distance between two points on the map is 74.25 cm, the actual distance between these points is
  
  
  
  0.75 cm = 6.48 km
  1 cm = 6.48/0.75 km = 8.64 km
  74.25 cm = 74.25*8.64 = 641.52 km

• Q) In a family there are some boys and girls. All boys told that they are having equal no of brothers and sisters and girls told that they are having twice the no. of brothers than sisters. How many boys and girls present in a family?
  
  A) Answer can be assumed from the given options.
  Only case/option A satisfies both the conditions:
  Condition 1: 1/each boy says he has equal brothers and sisters. So if he has 3 sisters and 3 brothers excluding him then in total there are 4 boys and 3 girls.
  
  Condition 2:If a/each girl says she has twice no of brothers than sisters, so going with option A satisfies this as well because excluding that girl (the one being considered) she has 2 more sisters and 4 brothers.
  So the answer is:
  4 Boys and 3 Girls..

• Q)Out of 7 children the youngest is boy then find the probability that all the remaining children are boys?
  
  A) Probability of a boy child is 1/2.
  Now as it is given that youngest child is a boy, then remaining are 6 children.
  Therefore: (1/2)*(1/2)*(1/2)*(1/2)*(1/2)*(1/2) =1/64

  a) 11 b) 7 c) 10 d) 12
  
  SOLUTION: f1: f2=6 :5
  
  5 *f1= 6 *f2
  5*f1 - 6* f2 =0 ---------(i)
  f1 + f2= 55 ---------(ii)
  
  solving this questions...
  we get:
  f1=30 and
  f2=25
  
  now suppose after x years ration would be 8:7
  (f1+ x) :(f2 +x) =8:7
  and we have already got yhe value of f1 and f2, by putting we will get the value of x,
  which is 10.

• In a family there are some boys and girls. All boys told that they are having equal no of brothers and sisters and girls told that they are having twice the no. of brothers than sisters. How many boys and girls present in a family?
  a) 4 boys and 3 girls b) 3 boys and 4 girls c) 2 boys and 5 girls d) 5 boys and 2 girls
  
  Answer with explaination:
  
  1. Each of the boy is being told that they have equal no of bro and sis. So its conclusive that he is not being included and hence the number of boy is one more than girls.------ b=g+1----- eq1
  
  2. Each girl is told that she has brothers double the number of sisters. Oviously she is excluded, but in equation if we include the girl then----- b=2(g+1)---- eq2
  
  So solving eq1 n eq2 we get g=3 n b=4.
  I know this approach is lenghty and choosing straight from 4 options by trial n error is more productive.... but still call me old fashioned.

  Ans : 56
  
  There are 8 toppings and you have to use 2 toppings ... for example you have 8 toppings like cheese, panner, chicken,tomato,capsicum,corn,onion,mushroom... you have to choose 2 toppings so 1.cheese + panner 2, cheese + chicken 3. cheese + tomato, 4.cheese + capsicum 5. cheese+corn 6.cheese+ onion 7 cheese + mushroom like that you make 8*7 = 56 ans.
