The greater of the two numbers whose product is 900 and the sum exceeds their difference by 30 is

• 60

• 75

• 90

• 100

A.

60

Let the numbers be x and y where x > y.
According to the question,
(x + y) -  (x - y) = 30
⟹   x + y - x + y = 30
⟹     2y = 30 208 Views

Let 0 < x < 1. Then the correct inequality is

• • • • C. Given,
0 < x < 1
Multiply by x
⟹   0. x < x. x < 1. x
⟹    0 < x2 <  x
Again,
x < 1  1067 Views

The sum of three positive numbers is 18 and their product is 162. If the sum of two numbers is equal to the third number, then the sum of squares of the numbers is

• 120

• 126

• 132

• 138

B.

126

Let the three numbers be x, y and z.
According to the question, we have three equations
x + y + z = 18               ...(i)
xyz = 162                      ...(ii)
and x + y = z                 ...(iii)
From equation (i),
z + z = 18
⟹   2z =  18 ⟹  z = 9
∴     xyz = 162
⟹   xy = 162/9 = 18    ...(iv)   421 Views

4.

• 9 only

• Both 3 and 9

• All of 3, 6 and 9

C.

Both 3 and 9

Let the 3-digit number be 100x + 10y + z.
Sum of the digits  = x + y + z
According to the question,
Difference
= 100x + 10y + z - (x + y + z)
=  99x + 9y
= 9(11x + y)
Clearly, it is a multiple of 3 and 9.

In a division sum, the divisor 'd' is 10 times the quotient 'q' and 5 times the remainder 'r'. If r = 46, the dividend will be

• 5042

• 5328

• 5336

• 4276

C.

5336

Divisor (d) = 5r = 5 x 46 = 230
Now,
Divisor (d) = 10 x quotient (q) Dividend  = Divisor x Quotient  + Remainder
= 230 x 23  + 46
= 5290 + 46 = 5336
