B.

Detailed Solution for RRB Group D Mock Test - 6 - Question 1

Let the present ages of Sushama and Karishma be 6x and 7x respectively.

or 56x + 64 = 54x + 72
x = 8/2 = 4
Required ratio

RRB Group D Mock Test - 6 - Question 2

The solution of the equation x-y = 0.9 and 11/2 (x+y)=1 is

A.
x=3.2,y=2.3
B.
x=2.3,y=3.2
C.
x=1.0,y=0.1
D.
x=2,y=1.1

Detailed Solution for RRB Group D Mock Test - 6 - Question 2

The given system of equation is
x - y = 0.9 = 9/10 ...(1)
and 11 /2(x + y) = 1
⇒ x + y = 11/2 ...(2)
Adding (1) and (2), we get
2x = 9/10 + 11/2
⇒ 2x = 9 + 55/10 = 64/10
⇒ x = 32/10 = 3.2
When x = 3.2, we get
3.2 - y = 0.9 (using(1))
⇒ y = 3.2 - 0.9 = 2.3
Thus, the solution of system of equation is x = 3.2 and y = 2.3

A.
5 ohms
B.
10 ohms
C.
20 ohms
D.
40 ohms

Detailed Solution for RRB Group D Mock Test - 6 - Question 34

Resistance is directly proportional to the length of the wire, its resistivity and inversely proportional to the cross-sectional area.
WIRE I
Let the length = L
Resistivity = R
Diameter = D
∴ Total Resistance ∝ L x R/ D²
WIRE II
Length = 2L
Resistivity = 2R
Diameter = 2D
∴ Total Resistance = 2L x 2R / 2D x 2D = LR/D²
∴ WIRE I : WIRE II = LR/D² : LR/D² = 1 : 1
i.e. Resistance of WIRE Z_B is also 10Ω
