(1) 147       (2) 279       (3) 312      (4) 207          (5) 183.

Solution:

Explanation:   100% of 15 = 15
              200% of 15 = 30
10% of 15 = 1.5 i.e.      30 + 1 = 200% + 7% (approx.) = 207 
Note: By practice, we can able to do these calculations without using a pen.

(1) 14700       (2) 14000      (3) 13000     (4) 12050          (5) 18300.

Sol:
Average percentage of males = (30 + 55 + 60 + 40 +25) / 5 = 210 / 5 = 42%

  • 42/100 × 35000
  • 14700

1.3) What is the total number of males in organization A & C together?

(1) 8400       (2) 8200       (3) 8000      (4) 7800          (5) 7200.

Sol:
(18/ 100 × 30/100   + 31/100 × 60/100) × 35000
=> (540 + 1860) × 3.5
=> 2400 × 3.5
=> 240 × 35
=> 8400
