If in a class test, A got 129.5 marks which are 70% of the B’s marks and B got 25% more marks than C while C got only 74% marks. Calculate the total number of marks for which the test was held.
1). 180
2). 200
3). 150
4). 250
A got 129.5 marks which is 70% of B’s marks
⇒ B’s marks = (129.5 × 100)/70 = 12950/70 = 185
B’s marks are 125% of C’s marks
⇒ C’s marks = (185 × 100)/125 = 18500/125 = 148
C got only 74% marks
⇒ Total marks = (148 × 100)/74 = 14800/74 = 200
∴ Total marks for which the test held is 200.
