Answer : A
Explanation
let 254 * x * 8= 95504. Than , x = 95504/ 254 * 8 = 47.
Answer : B
Explanation
given exp = 7+7+1/(21/7) = 15/3 = 5
Answer : B
Explanation
given exp= (1000-4/ 999)*999 = (999000-4 )= 998996
Answer : B
Explanation
given exp . = (4*5*6+5*6+12+6)/(1*2*3*4*5*6) = (120+30+12+6)/(1*2*3*4*5*6) =168/(2*3*4*5*6) = 7/30
Answer : A
Explanation
1/(1+ 1/ (1+1/x)) = 2 ⇒ 1/(1+x/(x+1)) = 2 ⇒ (x+1)/ (2x+1) = 2 ⇒ x+1= 4x+2 ⇒ 3x= -1 ⇒ x= -1/3
Answer : A
Explanation
given exp. = (1- 1/2) (1-1/3 ) ( 1- 1/4) ...{1- 1/(n-1)}(1- 1/n) = 1/2 * 2/3 *3/4 *...*(n-2)/(n-1)* (n-1)/n = 1/n
Answer : C
Explanation
(2/a + 1/b) = (a +2b)/ab = 6/ 4 = 3/2.
Answer : D
Explanation
on solving a+b = 5 and 3a+ 2b = 20 , we get a =10 ,b = -5 ∴ (3a+b) = (3*10-5) = 25
Answer : B
Explanation
given exp. = (a+b)2 +(a-b)2/ (a2+b2), where a = 856 , b = 167 = 2 (a2+b2) /(a2+b2) = 2
Q 10 - 1/4th of Naresh money is equal to 1/6th of Suresh money. If the joint amount of Naresh and Suresh is Rs. 600 then what should be the differences between both amounts?
Answer : C
Explanation
1/4 *x = 1/6 *y = h . then , x= 4h and y = 6h 4h+6h = 600 ⇒ 10h= 600 ⇒ h = 60. Required difference = Rs. (6h-4h) = 2h = Rs. (2*60) = Rs.120.
