Question

51. (1)( because ) CP of an article ( =₹ 800 )
and ( quad ) Gain ( %=12.5 % )
( therefore ) SP of an article ( =frac{C P times(100+text { gain } %)}{100} )
[
begin{aligned}=frac{800 times(100+12.5)}{100} & frac{8800 times 112.5}{100}=₹ 900 text { and discount } %=10 % end{aligned}
]
Hence, marked price of the article ( =frac{S P times 100}{100-D %} ) ( =frac{900 times 100}{100-10}=frac{900 times 100}{90}=₹ 1000 )

# O TUV is of 10%, a 800 a 51. The cost price of an article is After allowing a discount of 10 gain of 12.5% was made. Then, marked price of the article is RRB NTPC (Phase 1) 2016 (1) 1000 (2) 1100 (3) 1200 (4) 1300
