Answer : B
Explanation
35614 - 26889 = 8725 ∴ Given exp. 8725 / 25 = 8725/ 25 = 349.
Answer : C
Explanation
(let 20 +8*1/2 )/ (20-x) = 12 then (20+4)/(20-x)= 12 ∴ 240- 12x= 24 ⇒ 12x =(240-24) = 216 ⇒ x =18
Answer : B
Explanation
given exp= (1000-4/ 999)*999 = (999000-4 )= 998996
Answer : C
Explanation
Give Exp. = 3/4/ 9/4 of 2/3 - ( 1/6 ) / (5/6) * 10/3 + 5/6 = 3/4 / 3/2 - 1/5 * 10/3 + 5/6 = 3/4 * 2/3 - 2/3 + 5/3 = 1/2 - 2/3 + 5/6 = (3-4 + 5 ) / 6 = 4/6 = 2/3
Answer : A
Explanation
given exp. = { 1+ 1/ (1+1/(4/3)} /11/7
= { 1+ 1/( 1+3/4)} /11/7
= [ 1+ 1/(7/4)]/11/7
= (1+4/7) /11/7
= 11/7 /11/7
= 1
Answer : A
Explanation
given exp. = 1- [1-{1-(1-0)}] = 1- [1-(1-1)] = 1- [1-0] = 1-1= 0.
Answer : C
Explanation
a+ 1/b = 1 ⇒ a= (1-1/b) = (b-1)/b ⇒ 1/a = b/(b-1) = b+ 1/c = 1 ⇒ 1/c = (1-b) ⇒ c = 1/ (1-b) ∴ c+1/a = 1/(1-b)+ b/(b-1) = 1/(1-b) - b/(1-b)= (1-b)/ (1-b) =1
Answer : C
Explanation
x= y ⇒(1-a) = (2a+1) ⇒ 3a = 0 ⇒ a = 0.
Answer : B
Explanation
given exp. = (a+b)2 +(a-b)2 /ab = 4ab/ab = 4
Q 10 - If the average score of boys and girls is 71 and 73 but combined average of boys and girls is 71.8. How much percentage of girls is present in the class?
Answer : A
Explanation
If the number of girls is x than the number of boys in the class (100 -x). Then 73 x+ 71( 100- x) = 71.8 * 100 ⇒ 73x - 71 x = 7180 - 7100 = 2x = 80 ⇒ x = 40 Hence, it proves that 40% girls present in the class.
