2 R ----------------- 15
30
3 R + M ----------- 10
R = 2
M = 1
R + M = 600
3x = 600
x = 200
R = 400
M = 200
Q-(2) Sol-(5)
Initial area = 100 × 100 = 10000
Final area = 130 × 70 = 9100

5424 – 1056 + 3481 = ?
? = 7849
Q-(5) Sol-(3)
34 × 63 ÷ 93 + ?2 = 72
?2 = 49 – 24 = 25
? = 5
Q-(6) Sol-(2)
2785 – ? = 1710 + 630
2785 – 2340 = ?
? = 445
Q-(7) Sol-(1)
? = (4)2 = 16
Q-(8) Sol-(2)
55% of 2820 – 886 = 70% of 1680 – ?% of 1750
