A bag contain Rs 102 in the form of rupee, 50-paise and 10-paise coins...
Given:
Total amount in the bag = Rs 102
Ratio of rupee, 50-paise and 10-paise coins = 3:4:10

To find:
Number of 10-paise coins

Solution:
Let the common factor between the ratios be x.
Therefore, the ratio can be written as 3x:4x:10x.

Let the value of rupee, 50-paise and 10-paise coins be Rs 3x, Rs 2x and Rs x/10 respectively.

Total amount can be written as:
3x + 2x/2 + x/100 = 102
300x + 20x + x = 10200
321x = 10200
x = 10200/321
x = 31.8 (Approx.)

Number of 10-paise coins = 10x = 10*31.8 = 318

Therefore, the correct option is (d) 170.
