Answers :
1). Answer: a)
Let the number of male female and children in the village be 3x, 5x and 7x respectively.
Total number of persons = 3x+ 5x+ 7x = 15x
Number of illiterate males = (100 – 90) % × 3x
= 10/100 ×3x
= 3x/10
Number of illiterate females = (100 – 80) % × 5x
= 20/100 ×5x
= x
Number of illiterate children = 40% × 7x
= 40/100 ×7x
= 28x/10
Number of illiterate persons
= 3x/10+ x+ 28x/10
= 41x/100
Percentage of illiterates = (41x/10)/(15x)x100= 27.33%
2). Answer:a)
Principal= x
3). Answer: a)
Let there be ‘a’ boys and ‘b’ girls
b – a = 30—- (i)
110/100*b – 120/100*a = 24
1.1b-1.2a=24—– (ii)
Solving (i) and (ii) a = 90, b = 120
Total Students = a + b = 90 + 120 = 210
4). Answer: b)
Area of circle= πr2 = 22/7×r×r = 5544
R = 42
Circumference of circle = 2πr = 2×22/7×42 = 264
Circumference of circle = (Perimeter of rectangle)
Perimeter of rectangle = 264
2(l + b) = 264
2(75+b) = 264
75+b =132
B = 57 cm
Area of Rectangle = lb
=75×57 = 4275 sq.cm
5). Answer: a)
6). Answer: a)
7). Answer: b)
Let the CP of each mango be Rs.10
So CP of 500 mangoes = 500×10 = 5000
20% mangoes are rotten. Number of remaining mangoes = 80/100×500 = 400
At first he planned to sell the mangoes at 120/100×10 = Rs.12
New Selling Price = 150/100×12 = Rs. 18
SP of Remaining 400 mangoes = 400×18=7200
Profit = 7200 – 5000 = 2200
Profit Percentage = 2200/5000×100 = 44%
8). Answer: c)
9). Answer: d)
D1= x km
S1= 60 km/hr
T1=distance/speed
= x/60
D2 = 3x
S2 = 90 km/hr
T2 = x/30 = x/60
Total Time = x/30+ x/60 = x/20
Total Distance = 3x+ x = 4x
Average Speed = 4x/(x/20) = 80 km/hr
10). Answer: a)
