=1 + 10/19
= 29/19

Q 4 - 935421 x 625 = y. What is y?

Answer : C

Explanation

  y = 935421 x 625  = 935421 x (5)⁴  = 935421 x (10/2)⁴  = (935421 x (10)⁴)/(2)⁴)  = 935421 x 10000 / 16  = 9354210000 / 16  = 584638125

Q 5 - If 185 x 28 = 5180 then what is 51.8 / 18.5?

Q 6 - Aman can push at 5 km/hr in still Water. It the stream is running at 1km/hr, it takes him 75 min. to line to a spot and back. How far is the spot?

Answer : B

Explanation

Speed downstream = (5+1) km/hr=6 km/hr`Speed upstream = (5-1) km/hr=4 km/hr.`Let the required distance be x km. Then,`x/6+ x/4=75/60 = 5/4 => (2x+3x) =15 => 5x = 15 => x=3.`Required distance =3km.

Q 7 - A needs to pay Rs 1573 to B following 11/2 years and B needs to pay Rs 1444.50 to A following 6 months. In the event that the rate of hobby is 14% for each annum and both need to settle the record at this time, who will pay to the next and what amount?

Answer : D

Explanation

P.W. of loan on A = Rs ((100*1573))/(100+(14*2/3) )= Rs ((100*1573))/121= Rs 1300
P.W. of loan on B = Rs ((100*1444.50))/(100+(14*1/2) )= Rs ((144450))/103= Rs 1350
So, B will pay Rs. 50

Q 8 - The mathematical statement of a line going through the focuses A(- 1,1) and B(2,- 4) is:

Answer : B

Explanation

The equation of the line is (y-y₁)/(x-x₁) =
 (y₂-y₁)/(x₂-x₁)
 i.e., (y-1)/(x+1) = -4-1/2+1 ⇒ (y-1)/(x+1) = -5/3
 ⇒ 3y-3= -5x-5 ⇒ 5x+3y+2 = 0

Q 9 - Ajay , Bijender and chaman started a business and invested Rs. 20000 each partner .After the period of 4 month, some changes are made in investment just like Ajay withdraw Rs. 5000, Bijender and chaman both add 6000 each in the invested capital.
