New Delhi: The wholesale price index (WPI) based inflation dipped by 0.24 per cent to 5.67 per cent during the week ended April 30, from the previous week's level of 5.91 per cent. The fall in the year-on-year inflation was mainly due to a drop in prices of food and some manufactured products such as edible oils, according to data released by the ministry of commerce and industry.

During the latest reported week, the WPI rose by 0.1 per cent to 192.1 points due to rise in the index of manufactured products, even as fuel prices remained unchanged. The index was 181.8 points in the year ago period.

The fuel, power, lights and lubricants' group index stood firm at the previous week's level of 293.2 points while the index of manufactured products group rose by 0.2 per cent to 170.8 points due to costlier food products, chemicals, non-metallic minerals, basic metals and transport equipment.

Among the primary articles' group, the food articles group index fell by 0.2 per cent to 190.3 points due to lower prices for eggs (five per cent) and wheat and fruits (one per cent each), while prices of fish-marine and urad rose by two per cent each and barley by one per cent.

The index of non-food articles group was up by 0.2 per cent to 179.4 points due to costlier raw rubber (four per cent), sunflower and groundnut seed (two per cent each) and safflower and raw silk (one per cent each).

Prices, however, declined in the case of linseed and soyabean (three per cent each), castor seed and niger seed (two per cent each) and fodder (one per cent each).

Among the manufactured products group, the food products group index was up by 0.2 per cent to 174.7 points due to six per cent hike in oil cakes prices, even as prices fell for rice bran oil, maida and sooji (three per cent each), atta (two per cent) and salt, imported edible oil, sugar, gingelly oil, khandasari and hydrogenated vanaspati (one per cent each).

The index for chemicals and chemical products index rose by 0.7 per cent to 187.3 points owing to increase in the prices of epoxy resins (67 per cent), benzene (28 per cent), liquid chlorine, methanol and soda ash (two per cent each).

A marginal increase in cement prices pushed up the non-metallic mineral products index by 0.1 per cent to 168.8 points. The index for base metals alloys and metal products group went up by 0.2 per cent to 222.3 points as bright bars became costlier four per cent and utensils by three per cent.

The machinery and machine tools group index fell by 0.1 per cent to 144.7 points due to cheaper colour television sets (five per cent) and electrolytic capacitors (two per cent). A one per cent increase in the prices of bus chassis pushed up the transport equipment and parts group index by 0.1 per cent to 158.8 points.
