#### Question No 5

Jimmy bought 60 Mangoes and 40 Apples. He found 30% of Mangoes and 10%  of apples were overripe. Find the number of fruit in good condition.

Solution!
Total fruit = 60 + 40 = 100
Overripe  Mangoes = 30% of 60
= 30/100 x 60
=18
Overripe Apples = 10% of 40
= 10/100 x 40
=4
Total number of overripe fruit= 18+4=22
Therefore Number of fruit in good condition= 100-22= 78
.

#### Question No 6

Choose or find odd letter group
VT , MQ , PR , DF , FG

Solution!
Putting A = 1, B = 2, ....... and so on, we have:
VT = V + T = 22 + 20 = 42 (even);
MQ = M + Q = 13 + 17 = 30 (even);
PR = P + R = 16 + 18 =34 (even);
DF = D + F = 4 + 6 = 10 (even);
FG = F + G = 6 + 7 = 13 (odd).

#### Question No 16

Which term comes next in the series:
YEB, WFD, UHG, SKI, ?

Solution!
Clearly, the first letter of each term is moved two steps backward to obtain the first letter of the next term.
So, the first letter of the missing term will be Q.
The second letter of the first, second, third, fourth terms are respectively moved one, two, three and four steps forward to obtain the corresponding letter of the subsequent term.
So, the second letter in the missing term will be O.
The third letter is alternately moved two and three steps forward to obtain the corresponding letter of the subsequent term.
So, the third letter in the missing term will be L.
Thus, the missing term is QOL.

#### Question No 23

What is the unit digit in(795 - 358)?

Solution!
Unit digit in 795 = Unit digit in [(74)23 x 73]
= Unit digit in [(Unit digit in(2401))23 x (343)]
= Unit digit in (123 x 343)
= Unit digit in (343)
= 3
Unit digit in 358 = Unit digit in [(34)14 x 32]
= Unit digit in [Unit digit in (81)14 x 32]
= Unit digit in [(1)14 x 32]
= Unit digit in (1 x 9)
= Unit digit in (9)
= 9
Unit digit in (795 - 358) = Unit digit in (343 - 9) = Unit digit in (334) = 4.
So, Option B is the answer.

#### Question No 28

The sum of all two digit numbers divisible by 5 is

Solution!
Required numbers are 10, 15, 20, 25, ..., 95
This is an A.P. in which a = 10, d = 5 and l = 95.
tn = 95        a + (n - 1)d = 95
