1. Manoj sold an article for Rs. 15000. Had he offered a discount of 10% on the selling price, he would have earned a profit of 8%. What is the cost price?
Rs. 12500
Rs 13500
Rs. 12250
Rs. 13250
None of these
Solution:
SP = Rs. 15000m, if Manoj offered a discount of 10%
Then, new SP = 15000 – 1500 = Rs. 13500
∴ CP =(SP ×100)/((100 + 8) )=(13500 × 100)/108 = Rs. 12500

4. Mr. Shirke distributes the money he has among his 2 sons, 1 daughter and wife in such a way that each son gets double the amount of the daughter and the wife gets double the amount of each son. If each son gets Rs. 8500, what was the total amount distributed?
Rs. 38250
Rs. 34250
Rs. 38500
Rs. 32500
None of these
Solution:
Each son get Rs. 8500.
∴ 2 sons will get = 2 × 8500 = Rs. 17000
1 daughter gets = 8500÷2 = Rs. 4250
Wife gets = 8500 × 2 = Rs 17000
∴ Total amount = 17000 + 4250 + 17000 = Rs. 38250

8. A sum of money is divided among W, X, Y and Z in the ratio of 3 : 7 : 9 : 13. If the share of W and Y together is Rs. 11172, then what is the difference between the amounts of X and Z?
Rs. 7672
Rs. 6834
Rs. 5586
Can’t be determined
None of these
Solution:
Let share of W, X, Y and Z are Rs 3x, Rs 7x, Rs. 9x and Rs. 13x. respectively.
W + Y ⇒ (3x + 9x) = Rs. 11172
X – Z = (13x – 7x) =11172/12×6= Rs. 5586

10. One of the angles of a triangle is two-third angle of sum of adjacent angles of parallelogram. Remaining angles of the triangle are in ratio 5 : 7, respectively. What is the value of second largest angle of the triangle?
25°
40°
35°
Can’t be determined
None of these
Solution:
An angle of a triangle =2/3×180°=120°
Remaining 180°-120° is the ratio of 5 : 7
So, 5x + 7x = 60 ⇒ 12x = 60 ⇒ x = 5
So, angles are 5 × 5 =25° and 7 × 5 =35° and 120°
So, value of second largest angle of triangle is 35°.
