10.If 10, 12 and ‘x’ are sides of an acute angled triangle, how many integer values of ‘x’ are
possible?
a) 7 b) 12 c) 9 d) 13 e) 11
Answer
1.Sum of the present ages of husband, wife and child = (27 x 3 + 3 x 3) years = 90 years.
Sum of the present ages of wife and child = (20 x 2 + 5 x 2) years = 50 years.
Husband’s present age = (90 – 50) years = 40 years.
2.Largest size of the tile.
HCF of 378 cm and 525 cm = 21 cms.
3.Murugan : Prasanna : Arun = (8000 × 6) : (4000 × 8) : (8000 × 8)
= 48 : 32 : 64
= 3 : 2 : 4
Kamal’s share = Rs.4005 ×2/9
= Rs.890
4.Required number of ways = (8C5 x 10C6)
= (8C3 x 10C4)
= 11760
5.P (getting a prize) =10/10+25 = 10/35 =2/7
6.Let the son’s present age be x years.
Then, man’s present age = (x + 24) years
= (x + 24) + 2 = x (x + 2)
= x + 26 = 2x + 4
= 22 years
7.Rs 72
8.6km
9.25 days
10.For any triangle sum of any two sides must be greater than the third side.
The sides are 10, 12 and ‘x’.
From Rule 2, x can take the following values : 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18,
19, 20, 21 – A total of 19 values.
When x = 3 or x = 4 or x = 5 or x = 6, the triangle is an OBTUSE angled triangle.
The smallest value of x that satisfies both conditions is 7. (10² + 7² > 12² )
The highest value of x that satisfies both conditions is 15. (10² + 12² + 15² )
When x = 16 or x = 17 or x = 18 or x = 19 or x = 20 or x = 21, the triangle is an OBTUSE angled
triangle.
Hence, the values of x that satisfy both the rules are x = 7, 8, 9, 10, 11, 12, 13, 14, 15. A total of 9
values
