Answer:-

1.Sol:- (3)

2.Sol:-
Compound Interest =

C.I =

2541 – 2000 = 541 unit = 2705
1 unit = 5
2000 unit = 2000 x 5 = Rs.10,000

3.Sol:- (3)

Let number of student is x.
Average = 68.5
Required number of student,
68.5x + 280 = 68.80x + 275.2
0.3x = 4.8
X = 16

4.Sol:- (3)

Surface area of rectangular park = 2 (lb + bh + hl)
So = 2 ( 12 x 10 + 10 x 8 + 8 x 12)
Surface area of rectangular park = 592 m^2
Area hole =

Required iron sheet = 592 – 38.5 = 553.5

5.Sol:- (2)

= 19

6.Sol:- (4)

7. Sol:- (2)

789y531x is divisible by 72 then it will also divisible by 8 and 9 individually
So last three digit is divisible by 8 so value of x = 2
And value of y = 1,
(3x – 5y) = (3 x 2 – 5 x 1 ) = 1

8.Sol:- (4)
