9(X - Y) = 45

X - Y = 5

Solution

Factorization of 399 = 3 × 7 × 19

Possible pairs of (a, b) = (57, 7), (21, 19), (399, 1), (133, 3)

The least possible sum is given by b=19, a=21

And the required sum is 2 + 1 = 3

Solution

Required percentage =(288+98+442+83+3.00)/(420+142+550+108+3.56) x 100%

=(914/1223.56) x 100%

=74.70%

Solution

Required percentage =(83+68+92+89+108) / (98+112+101+133)=440/444=110:111

Solution

Total expenditure in 2005 is = 336 + 133 + 520 + 89 + 2.96 = 1080.96

Solution

A.P. series with a=2, d=3

Let 62 be nth term,

∴ T_n = 62

We know that T_n = a + (n - 1) d

62 = 2 + (n - 1) 3

60 = (n - 1) 3

(n - 1) = 20

n = 21

Solution

In the given service the letters all same and subscripts follow this series:-

111, 112, 122, 222, 223, 233, 333, ….

Solution

A=01; B=02; C=03; … L=12; N=14 and Z=26

L=12 ⇒ 1+2 = 3

N=14 ⇒ 1+4 = 5

Z=26 ⇒ 2+6 = 8

Like that

R=18 ⇒ 1+8 = 9
