Ans 1: (Master Answer)
Let Cost price be ‘x’.
Selling price = x – 15% of x = 85x /100
85x /100 = 1275
So, x(cost price) = 127500/85 = Rs. 1,500
So, new selling price = 1500 + 10% of 1500
= 1500 + 150 = Rs. 1650
Answer-(D) Rs 1650
Let Cost price be ‘x’.
Selling price = x – 15% of x = 85x /100
85x /100 = 1275
So, x(cost price) = 127500/85 = Rs. 1,500
So, new selling price = 1500 + 10% of 1500
= 1500 + 150 = Rs. 1650
Answer-(D) Rs 1650
(C): 1 : 20 + 170 + 20 = 210
2 : 120 + 70 + 5 = 195
3 : 70 + 200 + 20 = 290
As, 290>210>195
So, 3 > 1 > 2
(D): Second multiple of 12 = 12 x 2 = 24
Third multiple of 8 = 8 x 3 = 24
Multiplying the second multiple of 12 by the third multiple of 8 = 24 x 24 = 576
(B): Let’s assume the number be X.
32 thousands = 32,000
14 hundreds and 26 tens = 1400 + 260 = 1660
According to question,
32000 – X = 1660
Or, 32000 – 1660 = X
Or, X = 30340
