Answer Key-
Q-(1) Sol-(1)
Speed of Car A = 448/8= 56 km/hr.
Speed of Car B = 558/9 = 62 km/hr.
Ratio = 56 : 62 = 28 : 31
Q-(2) Sol-(4)
x ×60/100 -60 = 60, x = 200
Q-(3) Sol-(2)
l : b = 4 : 3
2 (4 + 3) = 1050
1=75
l = 300 , b = 225
Area = 67500 m2
Q-(4) Sol-(3)
Ratio = A : B: C
= 20 : 24 : 15
Age of A = 118 ×20/59= 40 Years
Q-(5) Sol-(2)
According to question 1/25–1/50=1/50
Required time = 50 minutes
Q-(6) Sol-(4)
a + b + c = 45 ------- (i)
b + c + d = 48 ------- (ii)
d = 19 ------- (iii)
From eq. (i), (ii) and (iii)
b + c = 29
a = 16
Q-(7) Sol-(2)
8534 - 4672 + 4450 = ? + 2987
12984 - 4672 = ? + 2987
8312 = ? + 2987
8312 - 2987 = ?
? = 5325
Q-(8) Sol-(5)
414.34 - 24.44 = ? - 63.75
389.9 = ? - 63.75
? = 389.9 + 63.75
? = 453.65
Q-(9) Sol-(2)
(424 - 81.8) ÷ 5 = ? ÷ (-4)
342.2 ÷ 5 = ? ÷ (-4)
68.44 = ? ÷ (-4)
68.44 × (-4) = ?
-273.76 = ?
Q-(10) Sol-(5)
26 × 23 + 2720 ÷ 4 = 158.5 + ?
26 × 23 + 680 = 158.5 + ?
598 + 680 = 158.5 + ?
1278 = 158.5 + ?
? = 1278 - 158.5
? = 1119.5
