(4) 65.25

(5) 45.85

Answer Key-
Q-(1) Sol-(5)

11 × 1 + 1= 12
12 × 2 + 1= 25
25 × 3 + 1= 76
76 × 4 + 1= 305
305 × 5 + 1= 1526

Q-(2) Sol-(2)
+ 42, + 52, + 62, + 72, + 82,

Q-(3) Sol-(1)

3 + 5 = 8

8 + 5 = 13

13 + 8 = 21

21 + 13 = 34

34 + 21 = 55

Q-(4) Sol-(4)

+13, +23, +33, +43, +53

Q-(5) Sol-(3)

× 1 - 2, × 2 - 3, × 3 - 4, × 4 - 5, × 5 - 6

Q-(6) Sol-(2)
Let the cost price of the article = Rs. x
Marked price of the article = Rs. 100
According to the question,
100 × 80/100+ 100 × 60/100= 2x × 105/100
100 × 140 = 2x × 105
x = 200/3
Required percentage = 100×3×100/200= 150%

Q-(7) Sol-(2)
Let the speed of current = y km/hr.
Downstream speed of boat = (12 + y) km/hr.
Upstream speed of boat = (12 – y) km/hr.
According to the question,
12 + y = 24 – 2y
3y = 12
y = 4 km/hr.

Q-(8) Sol-(5)
P + Q = 7050 × 2
P + Q = 14100 … (i)
Q + R = 7700 × 2
Q + R = 15400 … (ii)
P + R = 8250 × 2
P + R = 16500 … (iii)
By adding equations (i), (ii) and (iii),
2 (P + Q + R) = 46000
P + Q + R = 23000 … (iv)
Subtracting equation (ii) from equation (iv),
P = Rs. 7600

Q-(9) Sol-(1)
(?)2 % of 650 = (20)2 + (4)2
(?)2 = 64
? = 8

Q-(10) Sol-(2)
