एक परीक्षा जिसमें अधिकतम अंक 500 है, A, B से 10% कम अंक प्राप्त करता है, B, C से 25% अधिक अंक प्राप्त करता है व C, D से 20% कम अंक प्राप्त करता है। यदि A को 360 अंक मिले हो तो D को कितने प्रतिशत अंक मिले?

A) 50               B) 70               C) 75               D) 80

Sol :

Let marks obtained by D = x
C's marks = 0.80x
B's marks = 1.25 (0.80x)
A's marks = (0.90) (1.25) (0.80x)
= 0.9x
But 0.9x = 360 ⇒ x = 400
Marks obtained by D
=

2.) A person can row a boat d km. upstream and the same distance downstream in 5 hours 15 minutes. Also, he can row the boat 2d km. upstream in 7 hours. How long will it take to row the same distance 2d km. downstream?

एक व्यक्ति एक नाव को d किमी. धारा के प्रतिकूल व इतनी ही दूरी को धारा के अनुप्रवाह में 5 घंटे 15 मिनट में खेता है। वह 2d किमी. को धारा के प्रतिकूल 7 घंटे में खेता है तो 2d किमी. को धारा के अनुप्रवाह में खेने में उसे कितना समय लगेगा?

A) 3.5             B) 14               C) 7                 D) 5

Sol:

Let the speed of boat and stream be x and y kmph respectively.
According to question
=5 hours 15 min. or 21/4hours  ......(i)
and  ..... (ii)
From eq. (i) and (ii)

Hence, the person will take hours to row 2d km. distance downstream in 3.5hrs .

A) 21               B) 23               C) 29               D) 31

Sol :

Let the greater and smaller number be x and y respectively.
4y = x + 5 ------ (I)
x = 3y+2 ------- (II)
From equation (I) and (II)
y = 7
x = 23

5.) The average of 8 numbers is 38.4. Out of these numbers, the average of 7 number is 39.2. The 8th number

8 संख्याओं का औसत 38.4 है। इन संख्याओं में से 7 संख्याओं का औसत 39.2 है। 8 वीं संख्या है-

A) 31.5                        B) 32.8            C) 33.7            D) 34.5

Sol :

Sum of 8 numbers = 38.4 × 8 = 307.2

and  = 28
or, x+y = 56 years__________(II)
From equation (I) and (II)
8 y = 112
y = 14 years, hence x = 42 years

7.) The diagonal of a rectangle is 17 cm long and its perimeter is 46 cm. Find the area of the rectangle.

A) 100             B)110              C) 115             D) 120

Sol :

2(l+b) = 46
(l + b)2 = (23)2
(l2  + b2 ) +2lb = 529
172 + 2lb = 529 =>  lb = 120
Area = l × b = 120 cm2
