Solutions:

Ans.1(2) 608, 618, 628, 638, 648, 658, 668,678, 680, 681, 682, 683, 684, 685, 686, 687,689, 698.
So, there are 18 such numbers.
Ans.2(5) Let number = x

Ans.3(1) Let smaller number = y
Greater no = x
According to question-
x × 14/100-y × 16/100 = 275 — I
x × -y× = 27
7x – 8y = 1350 — II
By solving I and II
x = 850, y = 575
Required Sum = 850+575 = 1425
Ans.4(4) Boys = 350 × 70/100 = 245
Girls = 350 × 30/100 = 105
Total fee = 105 × 550 + 245 ×(550×120/100 )
= 57750 + 245 × 660
= Rs. 219, 450
Ans.5(5) Let the third number = x
Then, Second number = 3x
First Number = 3X / 2
ATQ,
3X / 2+ 3x + x = 55 x 3
11X / 2 =165
x = 30
Numbers = 30, 90, 45
So, Second smallest Number = 45
Ans.6(1) A:B:C = 2:1:3
C = 1224 ×3/6 = 612
Ans.7(3)

required ratio=96x:96x:168x=4:4:7
Ans.8(3) Total number of students in School= L.C.M. (48,72,80,100)=3600
number of boys in school = 3600×2/3 = 2400
Ans. 9(3) Let the saving of Ramesh and varun be ‘3a’ and ‘2a’ respectively
similary, Expenditure of Ramesh and Varun be ‘3b’ and ‘4b’
We have to find, = 3a/3b = a/b
According to question-

Ans.10(5)

So, sum of their incomes = ( 15 + 9 ) × 1800 = 24 × 1800 = Rs. 43200
