Explanation:
S.P of 20 articles = Rs. 60,
Gain = 20%
C.P of 20 articles = Rs. (100/120 × 60) = Rs. 50
Rs. 50, he bought = 20 articles
Rs. 60, he bought = (20/50 × 60) = 24 articles
A. 3
B. 4
C. 5
D. 6
Explanation:
C.P. of 6 toffees = Re. 1
S.P. of 6 toffees = 120% of Re. 1 = Rs. 6/5
For Rs. 6/5, toffees sold = 6. For re. 1.
Toffees sold = 6 * 5/6 = 5
A. 3×2 + 5x – 2 = 0
B. 3×2 + 5x + 2 = 0
C. 3×2 – 5x + 2 = 0
D. 3×2 – 5x – 2 = 0
The quadratic equation whose roots are reciprocal of 2×2 + 5x + 3 = 0 can be obtained by replacing x by 1/x.
Hence, 2(1/x)2 + 5(1/x) + 3 = 0
=> 3×2 + 5x + 2 = 0
A. Rs.5
B. Rs.4
C. Rs.2
D. Rs.3
Explanation:
40*(40/100) = 16 — 64

D. 12800
Explanation:
Let the monthly salary of Aamir be Rs. x.
68% of x = 27200
=> x = (27200 * 100)/68 = 40000
His savings = 32/100 * 40000 = 12800.
A. 10%
B. 11%
C. 21%
D. 100%
Explanation:
Suppose I Purchased 110 books
C.P = Rs. (10/11 × 110) = Rs. 100
S.P = Rs. (11/10 × 110) = Rs. 121
Gain % = 21%
